God is gracious and it’s a good thing, too, otherwise there is no chance we could know Him and survive.
For by grace we are saved, but grace does not stop at salvation. Grace is not a past tense idea for the believer. God’s grace abounds.
Moses had the guts to ask God to reveal Himself to Moses. This took guts but Moses thought it would be ok because of grace. Moses begins his request with “if I have found grace in thy sight.”
Mr. A. W. Tozer quotes this verse to prove that once a man finds grace he has a desire to keep finding more. Read what Moses says:
“Now therefore, I pray thee, if I have found grace in thy sight, shew me now thy way, that I may know thee, that I may find grace in thy sight.”
Moses has found grace in God and uses that grace to ask for more grace. He giveth more grace and His grace abounds and His grace is sufficient. It is only by His grace that we can ask for grace!
