In Hebrew, the title "God Almighty" is written as El Shaddai and probably means “God, the All-powerful One” or “The Mighty One of Jacob” (Genesis 49:24; Psalm 132:2,5), although there is a question among most Bible scholars as to its precise meaning. The title speaks to God’s ultimate power over all. He has all might and power. We are first introduced to this name in Genesis 17:1, when God appeared to Abram and said, “I am God Almighty; walk before me and be blameless.”
God has many names and attributes. He is the Almighty (Genesis 49:25), the Creator of heaven and earth (Genesis 14:19), Builder of everything (Hebrews 3:4), the King of heaven (Daniel 4:37), God of all mankind (Jeremiah 32:27), and the Eternal King. (Jeremiah 10:10). He is the only God (Jude 1:25), the Eternal God (Genesis 21:33), the Everlasting God (Isaiah 40:28), and Maker of all things (Ecclesiastes 11:5). He is able to do more things than we can ask or even imagine (Ephesians 3:20). He performs wonders that cannot be fathomed and miracles that cannot be counted (Job 9:10). God’s power is unlimited. He can do anything He wants, whenever He wants (Psalm 115:3). He spoke the Universe into existence (Genesis 1:3). Furthermore, He answers to no one as to His plans and purposes: “All the peoples of the earth are regarded as nothing. He does as he pleases with the powers of heaven and the peoples of the earth. No one can hold back his hand or say to him: ‘What have you done?’" (Daniel 4:35).
When we see God as the Almighty, we are struck by His power and by the fact that He is indeed a great, mighty, and awesome God (Deuteronomy 10:17). The identity of God as Almighty serves to establish the sense of awe and wonder we have toward Him and the realization that He is God above all things without limitation. This is important in view of how He is described next in the Bible. In Exodus 6:2-3, God said to Moses, “I am the LORD. I appeared to Abraham, to Isaac and Jacob as God Almighty, but by my name the LORD I did not make myself known to them.” How is this significant? It is significant because God, whom we previously knew only as God Almighty, has now given a new, more personal and intimate name to Moses (and Israel). This desire on God’s part for a more personal relationship with mankind would culminate later when God Almighty sent His only Son to earth--God in flesh--to die on the cross so that a way for forgiveness of our sins could be provided. The fact that God Almighty would humble Himself in this way for us makes His name all the more remarkable.
