Physical limitations have very little to do with the cognizant abilities of the human mind. I have seen men come on the stage in wheelchairs, pick up a violin, and make strong men cry, “He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.” (Prov. 16:32)
I know of members of musical groups who suffer from severe anxiety, who can barely hold a conversation, but can scream up on the stage for hours in front of thousands. Lazarus sat at the gate of the rich man, (Luke 16:20) full of sores, full of the joy of the Lord, the small, ruddy young boy, who killed a giant, (1 Sam. 17:49) the Lord chose Gideon to fight the battle, not the other way around. The saying is true, God does not choose the qualified, He qualifies the chosen.
How many pastors have you met who believe that they have been called by the Lord, so they head off to seminary, Bible college if you prefer, become the associate pastor of a church, or perhaps the youth director, and eventually lead their own church, and then stay there for thirty years or more teaching the same people the same things from the Scriptures. There have been occasions of course where these men from these colleges have been used mightily, but not many, most moved up the ladder, if you will, got their own church, grow the congregation as the Lord wills, if it is a God-fearing church, and then that little group just grows old together.
But I have met other men, unschooled, unlearned, but called, most definitely called to serve, and their ministries spread far across the planet. I would venture a guess that most of the Lord’s greatest prayer warriors are invalid in some way, the physical limitations are no hindrance to a life devoted to intercessory prayer and praise of the Most High, Samson was more than likely not great in stature, those who serve the Lord to their fullest capabilities are those that the world mocks for their limited abilities, their size, their inability to fit in with what the world tells us a man or a woman should be. “But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty.” (1 Cor. 1:27)
Few of these men and women of God see any great value in themselves, not in relation to what the world says they should be, but in why the Almighty would choose them, there is no false humility in them, they simply understand that they are but dust. (Psalm 103:14) They know that what has been accomplished has been through them, not by them, and they are just as satisfied if someone else completes what they have attempted to start, the glory of God is the only goal, it is the Lord that brings the harvest.
We do not need to look back over our lives and see the great things that the Lord has used us for, we need only to see a life of submissive service.
My lovely wife enjoys leaving Gospel Tracts at the places that we go to, on shelves of the grocery market, department stores, even when we were in the past blessed with the opportunity to take vacations, I have lost count of the thousands that she has placed on shelves. When she arrives in heaven, how big of a crowd will stand before her to say thank you? Better yet, when she turns around, she will see the ones that not only produced these same little Gospel Tracts, but those that distributed them, that paid the money for them to be produced, and when they turn around, they will see Jesus, the author and finisher of our faith.
How much we desire to serve is how much we will be used to glorify the Lord, clay vessels have no function unless they are filled, pray to be filled to overflowing, in whatever way that He would desire.
