1Pe 5:6 Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time: Casting all your care upon him; for he careth for you.
The other day we looked at verses telling us to pray when afraid or anxious, and this is similar. God cares about us. He created the world for us and He created us and then He sent his only Son to be the sacrifice for our sins that would enable us to get to Heaven to be with Him. God is the perfect Father.
Psa 55:22 Cast thy burden upon the LORD, and he shall sustain thee: he shall never suffer the righteous to be moved.
God is big enough for all of our problems. We're even covered if we're not sure what to pray for, as long as we pray!
Rom 8:26-28 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God. And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
And look at that last verse - we know all things work together for good to them that love God. God can work anything for good, even the really terrible things and sufferings and evil this world holds.
