Galatians 3:26 and Genesis 15:6 NKJ ... Abraham believed God and it was accounted to him for righteousness. 

Romans 4:19-21 NKJ ... Abraham, not being weak in faith, did not waver [through unbelief] at the Promise of God, but was strengthened in faith, GIVING GLORY TO GOD, being fully convinced that what God had promised [him] He [God] was also able to perform.

The time has come for God's people to stop looking at outside sources and to look  to God as their Source of getting all of their needs met.   Some  people think: "If I only had GREAT FAITH like Abraham, I'd be able to get all my needs met." 

Abraham didn't have a complicated special faith.  He didn't have to go through spiritual calisthenics to produce the faith that he needed to take possession of the Promise that God had given him.  He simply received the Promise and believed in the faithfulness and integrity of God that He'd do exactly what He said He'd do.
