God enables us to carry out His plan for our life. When we fall short of accomplishing the goals He has set for us, it is not because He in some way failed to provide the necessary equipping. Instead, failure is usually the result of an obstacle within our heart—an attitude that short-circuits our faith. As a result, the flow of God’s power is hindered, and we cannot become the person He desires us to be.
Moses is a dramatic illustration of the disruptive potential of faith barriers. Called to one of the greatest missions in all of Scripture, the future leader responded with excuses for why he should not obey.
Excuses for disobedience haven’t changed much since Moses’ encounter with the burning bush. He tried to hide behind the same faith barriers that believers cite today: poor self-image (Ex. 3:11-12), ignorance about God (Ex. 3:13-21), self-doubt (Ex. 4:1-9), feelings of inadequacy (Ex 4:10-11), and fear of failure (Ex. 4:12-13). Each time he protested that the Lord had asked the wrong person—a slow-tongued shepherd of slavery lineage, who murdered a man and became a fugitive—God responded with a firm, persuasive rebuttal.
The theme of God’s answers is something all believers need to understand, just as Moses finally did—namely, that when we are called to serve, our strength, skill, and wisdom do not matter. Rather, it is the Lord who does the work through us. He doesn’t seek out the most qualified person for a particular job but instead calls men and women who are willing to surrender themselves to Him. When His strength works through their weakness, it is obvious that only God could have achieved the result.
