God has already "helped" us, and has told us, how to keep anxiety and fear to a minimum in our lives. He tells us to "trust Him" in His Word. Jesus told people many times, "do not fear," and "let not your heart be troubled." He has also given us His peace, and left us with His peace. The Father and Jesus could not tell us to do these things if we were unable to do them. We can stop being stressed out, anxious, and fearful because the Word of God says we can. Do we believe it?
Keeping our minds on the Lord will cause Him to keep us in perfect peace.
Isaiah 26:3New King James Version (NKJV)
3 You will keep Him in perfect peace,
Whose mind is stayed on You,
Because he trusts in You.
In the name of Jesus, I bless you with the life of God.
