Exodus 3:14 God said to Moses, “I am who I am.” And he said, “Say this to the people of Israel: ‘I am has sent me to you.’”
Let us not try to create controversy here. There are too many interpretations out there about what God meant when He said this to Moses. A proper understanding here is unlikely.
When God told Moses to tell the people of Israel that “I Am” sent him, there are no existing documents before Moses delivered the Pentateuch that says Israel had any understanding of what “I AM” means. We do not know what they thought.
When I say “I am a Christian” I know what I mean, but that is no guarantee that the hearer understands what that means without my words and actions matching my beliefs. Even then, that does guarantee perfect understanding. Imperfect beings seem to be incapable of perfect understanding.
For me Christianity is a growth process. I am not what I was 30 years ago, nor am I now what I will be in another year. If I am judged for what I said and did 30 years ago, it does not reflect who “I AM” today.
Malachi 3:6 “For I the Lord do not change;”
There is no need to finish that quote, this is enough to understand that the primary quality of the great “I AM” is consistency, even if we do not understand. God is perfect in form and character so there is no need for Him to change.
We need to change because we were not perfect to begin with, but have the potential to be changed if we are willing. Potential is the key to growth.
2 Corinthians 3:18 And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.
Christianity is not a mask we wear so that others cannot see what we are in reality. We are told not to mask our Christianity as if it is something to be ashamed of in this life.
Ephesians 2:5 even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—
Ephesians 2:8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God,
Grace is unmerited favor, if I didn’t deserve it, then perhaps they will believe they too can find salvation by faith in Jesus Christ even though they don’t deserve it either.
