To prepare for it, stay close to the Lord by purifying your heart and thoughts through the daily washing of the Word. Be careful not to forsake the Holy One of Israel. Soon the culmination of all things shall begin. Purify yourselves daily by the reading of the Word. Jesus is returning for a Holy and Spotless Church.
Today is the day of their salvation.
Time is short. You have no guarantee that you will even see tomorrow. If you die without receiving Jesus as your Lord and Savior, your eternal destiny is fixed. Remember that Jesus is returning for a Holy and Spotless Bride. Whether His return is today or 10 years from now is irrelevant since eternity is only a heart beat away for any of us.
