God does not just have the ability to perform His word, He is also able to perform His word. When it comes to having a full understanding of God’s ability. First we must check God’s track record if He had by any slight means failed in His abilities and if He has, then He can not be trusted but as long as He has never failed once then we must therefore be fully persuaded like Abraham to believe  God and hold Him by His words. 

  • God does not turn away from Him word

James  1:17 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, WITH WHOM IS NO VARIABLENESS, NEITHER SHADOW OF TURNING.

God is faithful to His word. Not like man that can not keep at his word when they promise a thing. God has no shadow of turning. You know shadow tells of the real image. This image here or shadow here may represent His heart. You know before a man can do a thing, it is first seen in his heart. So God has no shadow of turning. He won’t deny Himself. 

  • God hasten his word to perform it 

God speaking to Jeremiah about what he sees. He said… 

Jeremiah  1:12  Then said the LORD unto me, Thou hast well seen: FOR I WILL HASTEN MY WORD TO PERFORM IT.

For me, the only weakness I see that God have and is a good one there is, is, accept if He has not spoken it. Once it is out of His mouth I can trust Him to bring it to pass. Even if it demands waiting. 

One thing you need is to understand that God is able to perform His Word and once this is established in your heart. Then, it is be easy to believe God anytime He gives you His word.
