Jesus said:” do not worry about tomorrow; for tomorrow will care for itself. Each day has enough trouble of its own.” Matthew 6:34. It is a command, an instruction, of Jesus to those who follow Him, who put their trust in Him.
We cannot be trusting in Him, if we worry. Without faith it is impossible to please God. He works on the behalf of those who trust Him. Jesus said: “I will never leave, nor forsake you.” He is our Helper and He will take care of us. We must just trust in Him and not worry. It is written in Philippians 4:6,7 “Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. 7And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus.”
May Jesus bless you.
