Then Abram fell on his face, and God talked with him, saying: “As for Me, behold, My covenant is with you, and you shall be a father of many nations. No longer shall your name be called Abram, but your name shall be Abraham; for I have made you a father of many nations.” (Genesis 17:3-5)
When you compare the names Abram and Abraham, as written in Hebrew, you see that the difference is one letter called ה hei. This is the fifth letter in the Hebrew alphabet and is understood to signify breath (think of the sound someone makes when they’re breathing heavily). Thus we understand that, metaphorically speaking, this great change in Abram’s life came about when God breathed into him, so to speak.
It is reminiscent of man’s creation in the beginning; God formed him from the dust of the earth and then breathed into him the breath of life. At that point, he became a living soul capable of functioning in the purpose God had created him for. Likewise with Abram — now Abraham — he was empowered by the breath (Spirit) of God to do what he had been called to do.
The same is true for all of God’s people; we need God to breathe upon us and into us that we may be empowered to do all that He has commanded us to do. This is why the Messiah told the disciples to tarry in Jerusalem to receive the Holy Spirit before being sent into the world to be witnesses of His resurrection — they would need that power. This is how it has been from the beginning; God never calls us to do something unless He equips us to do it. Now that we have been energized by His Spirit let us go about doing His business and be the source of blessing He has called us to be.
Blessings and Shalom,
