Are you curious about End Time theology and wonder about the ultimate fate of all creation? Many Christians greatly anticipate the Lord Jesus Christ’s return. The book of Revelation has inspired many different theories and interpretations of what the end times will look like, however, one thing is certain - that God has a divine plan for us. Pure Flix features these End Times movie series that will give you insight and help you to trust in His plan:
In the first installment of “The Moment After” series, FBI agents Adam Riley and Charles Baker are called in to investigate after a mass disappearance of people. In the course of uncovering the truth, the agents stumble upon a vast government conspiracy that could change the world.
“The Moment After 2” continues the saga as now former FBI agent Riley reunites with his old mentor, Jacob Krause. Krause is the leader of a group known as “The Way”, a remnant of Christians who are facing the extermination of their faith. They are determined to fight against the New World Order to keep the word of God alive.
Based on the best-selling End Times series, these movies star Kirk Cameron as reporter Buck Williams in his search for the truth. In the wake of the sudden disappearance of millions of people around the world, the head of the United Nations steps in to broker peace among the people. However, Buck soon realizes that he may in fact be the Antichrist foretold in the Bible.
"Do not let your hearts be troubled. You believe in God; believe also in me. My Father's house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am.” John 14:1-3 (NIV)
Josh McManus is a traveling salesman who stumbles upon a robbery perpetrated by “The Barbarians”, an outlaw biker gang, and foils their plan. Suddenly, a strange flash appears in the sky, followed by crippling earthquakes. Along with the natural disaters, mysterious disappearances throws the world into chaos. Josh’s only goal is to get back home to his family, but to do so, he must get past “The Barbarians.”
In “Revelation Road 2”, Josh continues his quest to reunite with his family and is joined by three others struggling to make sense of what has happened. Josh and his group have also drawn the attention and ire of a local biker gang. In “Revelation Road 3”, a beleaguered politician asks Josh to find a mysterious figure known as the Shepherd who may be vital to the people of his small town.
Movies are a great way for explaining complex subjects in a short amount of time. While there are theatrical effects added for entertainment, End Times movies provide great insight into the underlying message of trusting in God’s divine plan. Still looking for more?

Cardiac e-consults may be an effective way to deliver value-oriented outpatient cardiology care in an accountable care organization. Initial results of cardiac e-consults have demonstrated high satisfaction among both patients and referring providers, no known adverse events, and low rates of diagnostic testing. Nevertheless, differences between e-consults and traditional consults, effects of e-consults on traditional consult volume, and whether patients seek traditional consults after e-consults are unknown.
We established a cardiac e-consult program on January 13, 2014. We then conducted detailed medical record reviews of all patients with e-consults to detect any adverse clinical events and detect subsequent traditional visits to cardiologists. We also performed 2 comparisons. First, we compared age, gender, and referral reason for e-consults vs traditional consults. Second, we compared changes in volume of referrals to cardiology vs other medical specialties that did not have e-consults. From January 13 to December 31, 2014, 1,642 traditional referrals and 165 e-consults were requested. The proportion of e-consults of all evaluations requested over that period was 9.1%. Gender balance was similar among traditional consults and e-consults (44.8% male for e-consults vs 45.0% for traditional consults, P = .981). E-consult patients were younger than traditional consult patients (55.3 vs 60.4 years, P < .001). After the introduction of cardiac e-consults, the increase in traditional cardiac visit requests was less than the increase in traditional visit requests for control specialties (4.5% vs 10.1%, P < .001). For e-consults with at least 6 months of follow-up, 75.6% patients did not have any type of traditional cardiology visit during the follow-up period.
E-consults are an effective and safe mechanism to enhance value in outpatient cardiology care, with low rates of bounceback to traditional consults. E-consults can account for nearly one-tenth of total outpatient consultation volume at 1 year within an accountable care organization and are associated with a reduction in traditional referrals to cardiologists.
Poststroke hyperglycemia (PSH) is common and has adverse effects on outcome. In this observational study, we aimed to describe the frequency and temporal profile of PSH using a continuous glucose monitoring system (CGMS) in patients with and without diabetes.
Fifty-nine patients with acute hemispheric ischemic stroke were prospectively studied with the CGMS, regardless of medication, admission plasma glucose value, and diabetes status. The CGMS records interstitial glucose every 5 min for 72 h.
On admission, 36% of patients had preexisting diabetes. At the earliest analyzed time point of 8 h from stroke onset, 50% of nondiabetic subjects and 100% of diabetic patients were hyperglycemic (≥7 mmol/l). This early-phase hyperglycemia was followed by a decrease in glucose 14–16 h poststroke when only 11% of nondiabetic and 27% of diabetic patients were hyperglycemic. A late hyperglycemic phase 48–88 h poststroke was observed in 27% of nondiabetic and 78% of diabetic patients. Thirty-four percent of nondiabetic and 86% of diabetic patients were hyperglycemic for at least a quarter of the monitoring period. Multivariate regression analysis demonstrated that diabetes, insular cortical ischemia, and increasing age independently predicted higher glucose values.
Poststroke hyperglycemia is common and prolonged despite treatment based on current guidelines. There are early and late hyperglycemic phases in nondiabetic as well as diabetic patients. Treatment protocols with frequent glucose measurement and intensive glucose-lowering therapy for a minimum of 72 h poststroke need to be evaluated.
Predictors of acute posttraumatic stress disorder symptoms following civilian trauma: Highest incidence and severity of symptoms after assault
Posttraumatic stress disorder (PTSD) is associated with significant morbidity following injury. The incidence and risk factors for PTSD are not well described in the civilian trauma population. We proposed to screen all trauma patients in the outpatient trauma clinic for acute PTSD symptoms and identify risk factors for PTSD.
We prospectively screened 1,386 injured patients who presented for follow-up in trauma clinic (January 2009 to September 2010) using an established PTSD screening test (PTSD Checklist-Civilian, PCL-C). A PCL-C score of ≥35, with a known sensitivity of >85% for PTSD, was considered screen-positive (PCL-C-POS). Backward stepwise logistic regression was used to determine independent risk factors for PCL-C-POS.
Over 25% of trauma clinic patients met the threshold for positive PTSD screen (PCL-C-POS). The highest incidence (43%) was in patients who sustained assault (blunt or penetrating). Regression analysis revealed that age <55 years, female gender, motor vehicle collision, and assaultive mechanism (blunt or penetrating, excluding self-inflicted or accidental injury) were independent predictors of PCL-C-POS status. As the severity of symptoms increased (higher PCL-C scores), the risk associated with assaultive mechanism significantly increased in a dose-response fashion (p < 0.05).
This study confirms the high incidence of acute PTSD symptoms in trauma patients and supports the feasibility of PTSD screening in the outpatient trauma clinic. Among all mechanisms of injury, patients who sustain interpersonal violence are at the highest risk of developing acute PTSD symptoms. These results suggest that PTSD screening in outpatient trauma clinic may allow early detection and referral of patients with PTSD.
