One of the first things God spoke to Abram was: "I will bless you." These words have been at the very heart of God's desire for all men and women. He is a giver and is committed to bringing His blessings to His people.

In establishing a covenant with Abram, God clearly stated what He would bring to him through this agreement.

Notice Genesis 12:
Now the Lord had said to Abram: "Get out of your country, from your family and from your father's house, to a land that I will show you. I will make you a great nation; I will bless you and make your name great; and you shall be a blessing. I will bless those who bless you, and I will curse him who curses you; and in you all the families of the earth shall be blessed."
(Gen. 12:1-3)
The Amplified Bible says:
I will make of you a great nation, and I will bless you [with abundant increase of favors]...."
He wants to bless and favor you.

Think about that: abundant increase of the favor of God. God considered it such a priority for His blessings and increase to be brought to mankind, He declared that it was the first thing He would do for Abram—if he would only obey Him.

As Abram began to obey God and to walk with Him, he saw the power of God's covenant in action. Immediately he would see the increase, which it brought him.

In Genesis 13, it tells of the abundance that Abram and his nephew, Lot, received from the Lord:
Now the land was not able to support them, that they might dwell together, for their possessions were so great that they could not dwell together.
(Gen. 13:6)
Their possessions had increased abundantly. It was more than they could contain as long as they stayed together.

If Abram was to continue to increase, he would need to go on with God and be separated from Lot.

The covenant brought an increase of possessions. But there would be more, God would give him land as far as his eyes could see.

He would give Abram descendants, land and increase of wealth as well as influence, all because he would continue to live by faith in the covenant between himself and God Almighty.
