If we trust in our worry more than we trust God we are sinning by our lack of faith in God, who has given us the richness of His constant abiding presence, for those who put their faith in Him.
We can be just as certain and worry-free about God’s love and protection. What is the evidence? It is the cross, where God fully expressed His love for us. Since Jesus overcame death, can He not help us overcome worry about things that will probably never happen? We should turn worry into gratitude for all the times He has seen us through difficulties. Worries flee before a spirit of gratitude and the Lord is pleased when we trust Him (1 Peter 5:7).
