If you keep worrying about tomorrow’s issues or things that you cannot change, you will just give yourself high blood pressure for nothing.
Why don’t you fix your mind on the Lord instead, ask Him for what you need and thank Him for the answer and for peace in your heart.
‘ You will keep him in perfect peace,
Whose mind is stayed on You,
Because he trusts in You’- Isaiah 26:3
‘Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus’ – Phillipians 4:6-7
God is trustworthy and He promises to keep us in Peace as we look up to Him. He cannot lie or fail.
You were not designed to worry. You were designed to trust. Act according to design.
