We worry because we don't know. We worry because of uncertainty and our lack of believe in our own ability. God has a solution to worry. Trust that He has a plan and that His plan and ability is better than ours. And then pray to God and ask for peace and for understanding and for the ability to deal with anything ahead.
Lord, help me to trust in Your plan and thank you that you not only have a plan but it is vastly better than my desires.
