Ask the businessmen and they will tell they have the ups and downs cycle in their business. Thus is also the life of the people which God created through our Lord Jesus Christ. They have their ups and downs in their short life on earth. God and our Lord Jesus have seen all their bad and good habits since Adam and Eve. They have bad mood, good mood, ugly mood, mood to kill people, mood to hurt people, mood to talk about people, they stay away from doing good, stay away from God and stick to their evil ways to keep their short life happy.
Christians do have their ups and downs in their life.
We know of people who have turned to God, repented of their sins only to return to their evil ways again. We also know of Christians who have strayed away from the faith, converted into other faiths and who have closed their eyes to the miracles shown unto them by God and now are sinning to the maximum. But some Christians are different. They are like the weather in some places where it is good all year around. They are like the companies that reap profits even in bad times and they are like the smart share market investor who makes money even in bad times.
