What could we accomplish in serving God if we had better natural ability? Moses had all kinds of excuses, including not being able to speak well, to get out of serving God by leading the Israelites out of Egyptian bondage (Exodus 3:7 - 4:12). When God provided a solution to every supposed challenge and deficiency, Moses finally got to the root of the problem when he pleaded with God to just send someone else (4:13). Unwillingness, rather than inability, was the real problem, and that is usually the case today. "So the anger of the Lord was kindled against Moses..." (4:14). The apostle Paul prayed for the removal of some "thorn in the flesh" that he was experiencing. The answer to his prayer was basically, No! The Lord explained, "My grace is sufficient for you, for My strength is made perfect in weakness" (2 Corinthians 12:7-9). The Lord can effectively use us in spite of our supposed inadequacies, if we'll let Him.
What could we accomplish in serving God if we had greater resources? We often have greater resources than we realize or want to admit. Many are reluctant to commit their own resources, missing the lesson that God gives us the initial blessing and promsies to continue to bless us according to how we give back to Him from what He has already given to us (Luke 6:38). With blessing goes responsibility. We are responsible for using the resources with which God blesses us in His service and to His glory. But God Himself is our greatest resource (Ephesians 3:20). He can provide where we lack. We need to remember that the power is ultimately in God, not in our pitiful material resources.
We need to stop making excuses for not serving God as we ought for lack of time, ability, or resources. We need to simply start serving Him to the best of our ability with all that we have and all that we are. We need to just serve Him!
