Well my friend why not lead the way by example.
Scripture teaches us: 1 Peter 5:6 Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time: 7 Casting all your care upon him; for he careth for you.
You have NOT cast all your care on the Lord!
You admit that you are scared that things may not work out right for you. (You hold on to your cares)
You also have refused to repent of your sin of fear. That is pride.
So don't you think you should lead the way in showing us how to repent... and stop sinning by forsaking your pride... and asking God to forgive you of your doubting Him and being scared that He won't see you through?
