Then the Lord took Abram outside and said to him, “Look up into the sky and count the stars if you can. That’s how many descendants you will have!” And Abram believed the Lord, and the Lord counted him as righteous because of his faith. Genesis 15:5-6(NIV)
Abram believed the Lord concerning what He told him. This means he agreed with Him. Abram agreed with God. What the Lord said, Abram said. What the Lord saw Abram saw. Abram said and saw what the Lord said and saw. Because Abram agreed with God, the Lord counted him righteous. The key to experiencing and enjoying God and his blessings is agreeing with Him. We walk with God by saying the same thing as Him, seeing as He sees. God says His Word, and He sees His Word.
When God said to Abraham that he had made him the father of multitudes, before Abraham physically had a child, before old Abraham and old barren Sarah showed and experienced the slightest physical change in their bodies, God was convinced that what He had said was already done.
The Lord told the prophet Jeremiah that “He watches over His Word to perform it” Then said the Lord to me, You have seen well, for I am alert and active, watching over My word to perform it. Jeremiah 1:12
Since God’s full constant attention is on His Word, we agree with God by agreeing with His Word. We see eye to eye with the Lord by looking to and continuing in His Word.
God told the Israelites that He had already given them the land of Canaan as their inheritance. Nevertheless, after they sent their spies there, they brought an evil report concerning the land saying they were not able to get in and possess the land, and they (Israelites) were in their own sight like grasshoppers before the enemies. What they said and saw totally contradicted what God said. They disagreed with God. They all died in the wilderness except two men namely Joshua and Caleb.
To agree with God is to act like His Word is true.
When His Word tells us that we can do all things through Christ who strengthens us (Philippians 4:19) then that’s the truth regardless of how we feel.
