God called Moses to do a great work for Him that would also bless the Israelites. Moses’ response to this awesome invitation was to offer excuses for why he couldn’t obey. This kind of attitude—which I call a “faith barrier”—can thwart us spiritually.
In Moses’ life, we see areas of weakness that can create such a faith barrier:
Poor self-image. When God gave the command to go to Pharaoh and lead the Israelites out of Egypt, Moses’ immediate response was to say, “Who am I?” (Ex. 3:11). Perhaps he was thinking of his occupation as a lowly shepherd living in Midian. Maybe he was referring to his upbringing and separation from his birth family (Ex. 2:1-4). Or he might have been recalling his past, when he killed an Egyptian and had to flee (Ex. 2:12). Whatever Moses’ objection was, the Lord answered with a wonderful promise: “I will be with you” (3:12).
Ignorance of God’s greatness. In order to carry out God’s plan, we need to believe fully in the One who has called us. When Moses questioned his assignment again, the Lord answered by revealing Himself as the great I AM and the One who had promised to rescue the Israelites (vv. 14-17). By trusting in the character and promises of almighty God, Moses would be able to carry out this seemingly impossible assignment.
Faith barriers hinder the flow of divine power in our life, slow spiritual growth, and prevent us from fully carrying out the Father’s will. We must remember who He is and where power comes from. We know that our heavenly Father is sovereign over all, and His Spirit empowers us to follow through in obedience.
