WHAT CAUSES STRESS?
Stress is caused by doing things in your own strength. Two things will eliminate stress: 1) Letting God do it through you instead of doing it yourself and 2) Realize that God is in charge of the results. Your stress will melt away when you realize that both the effort and the outcome are in God’s hands!
Stress can actually be a form of arrogance. Be very careful thinking it all depends on you and not on God.
