In order to remain calm during turbulence on a passenger airliner, you have to TRUST in the WORDS of a PILOT you do not see. When last did you inquire about a pilot who flew your flight or uber/taxify/black cab/minicab/taxi/bus driver before trusting them for your safety? I bet you don’t do that. Do you?

However when it comes to God, we have different reservations. SAD. “what if…?” becomes a major consideration. Interesting, isn’t it?
If only you could trust God as much as you do with human (who are prone to making errors/mistakes), you will see His marvelous works in your life.
You keep him in perfect peace whose mind is stayed on you, because he trusts in you. Trust in the Lord forever, for the Lord God is an everlasting rock
(Isaiah 26:3-4, ESV)
When you find yourself in a situation that’s over your head, don’t give in to fear, but trust that God is able to sustain you in the midst of trouble.
Be still, and know that I am God!
(Psalm 46:10)
God will keep you in Perfect Peace when you Trust in Him. His records are visible in the pages of scriptures thus when you trust in Him, you will never be put to shame. And in the midst of storms of life, you can be sure that He will keep you safe.
