Isaiah 43:10-11 “You are My witnesses,” declares the Lord, “And My servant whom I have chosen, So that you may know and believe Me And understand that I am He. Before Me there was no God formed, And there will be none after Me. 11 “I, even I, am the Lord, And there is no savior besides Me.
Introducing Divine Aseity (A-say-i-tee)
When you read through Isaiah 43-44, you find celebrated a characteristic of God that is unique to Himself - a trait that Bible teachers call "aseity" (a-say-itee). I like to think of this eternal quality of God as being "God's Godness" or "what makes God - God". Theologian Dr. R.C Sproul writes concerning God's Divine Aseity:
Why God's Divine Aseity is so important
The modern classic book on the doctrine of God by J.I Packer, "Knowing God", lays out the practical and profound reasons why Christ-followers ought to include God's aseity in their everyday lives:
To begin, Divine Aseity is important for the worship songs we commonly sing. One of my favorite hymns that celebrates the Aseity of God is the song "Come Thou Fount of Every Blessing." The lyrics of the hymn begin as follows:
2. Aseity is essential to understanding God in His Word
Another reason we could cite as to why God's Aseity is so important is in how the revelation of Himself to us in His Word requires Him to possess this quality. Isaiah brings out three main titles of God: Savior (Isaiah 43:3), Creator (43:15) and King of Israel (43:15). As you read these chapters, you find a repeated phrase that speaks of God's Aseity - namely that God is the only Lord, and there is no other, neither before nor after Him. (Isaiah 43:10-11; 44:6-8). God's Aseity insures that God is the sole source of salvation, the sole source of all things as Creator and the Sole King over His people.
3. Aseity is essential to waging war on worldliness
Isaiah then contrasts God who is Aseity to that of man made idols that are not gods at all (Isaiah 44:9-20). Quite the opposite of Aseity is the fact that idolatry is foolishness, since men take blocks of wood or stone and take half for firewood and half to make an image. Those false gods cannot save, only condemn.
4. Aseity is essential for the work of salvation
Only the God that is Aseity, the God that is His own Source of life and eternal power, can redeem and forgive (Isaiah 43:10-11;44:21-28). For example, when you turn to Colossians 2, you discover two essential truths about Jesus Christ: He being truly God and truly man. Take everything you just learned about God in Isaiah 43-44 and apply it to the Son, Jesus Christ. The Lord Jesus Christ, touching His Divinity, shares the same exact qualities with the Father, being the "fulness of Deity in bodily form" (Colossians 2:9).
Celebrate God's aseity. Praise Christ today for His aseity - the quality that makes Him an equal sharer with the Father and the Spirit and thus the source of your salvation. Also praise Him that He came to share in your humanity so that He could shed His blood for you and rise from the dead.
