But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. (James 1:6 NIV)
Act on the wisdom God has given you.
Believe that He has equipped you to do it.
Commit to NOT worry and fret over it.
Jesus slept through the storm because he was at peace on the inside. The peace of God doesn’t depend on outward circumstances but on an inward relationship. Choose to trust God. He will get you safely to the other shore.
Doubt your doubts, not your God.
