"Trust in the Lord with all your heart and lean not on your understanding, in all your ways submit to him, and he will make your paths straight", as is written in Proverbs 3:5 -6.
We should put all our hope and trust in God because asides Him, we are too weak to do anything, even though we think we are strong enough to. God created us and all the affairs of our lives are in the palms of His hands. So, who else is better to handle our lives than Him? He alone handles the universe, and nothing is too much for Him to handle.
He wants us to have no doubts in our hearts when we come before Him with our requests. He said in Jeremiah 32:27, "Behold, I am the God of all things, is anything too hard for me?" He has all the power in this world. Do not be afraid to trust Him with anything, for He is our friend and creator.
There is no need trusting in creatures, when the creator Himself beckons on you to come to Him. He said in Matthew 11: 28, “Come to me, all you who are weary and burdened, and I will give you rest".
Have faith in God and doubt not. Even if our faith is as small as a mustard seed, we can tell the mountain to move, and it will move (Matthew 17: 20). Everything belongs to Him, and nothing intimidates Him. Believe in Him and He will uplift you from whatever is your situation.
