He can. ( Psalm 23 )

Augustus Herman Franke(1662- 1727) ,wrote of a time when he was in utmost extremity financially,but as he thought on God's greatness,his heart was strengthened in faith. He wrote,'What an excellent thing it is when we have nothing, and can rely upon nothing, but yet are acquainted with the living God,who made heaven and earth , and place our confidence alone in Him, which enables us to be so tranquil even in necessity!.He tell how he needed money that day to pay the workmen's wages ,but when he got home he was told there was no money there,but he declared that he had faith in God to meet the need. No sooner had he uttered these words someone arrived with 30 dollars from an unknown source.He asked the overseer how much was needed,he replied 30 dollars'.I read this in Herbert Lockyer's book in the Psalms,one is greatly strengthened in ones faith when we read these things, for the God who met the need of that person can meet the need of anyone of His children,for we read.' My God will meet all your needs according to the  riches of his glory in Christ Jesus' ( Philippians 4 v 19 )
