Soldier of The Cross, you don't have to do it all yourself.
The Amplified Bible says:
"The Lord is my Shepherd [to feed, guide, and shield me], I shall not lack."
Psalm 23:1
Is it true? You won't taste His provision until you stand before Him and acknowledge that He is the Provider and you trust Him. Then, if you have to knock on hundreds of doors without one opening, you will still have the supernatural assurance that regardless of the "now", you will not lack.
He has never let down any Soldier who has trusted Him and waited for Him.
