In reality, every leader follows someone who trod the path before him. We follow Christ. Though we cannot literally see Him, we walk with Him. However, we can read what He did and taught because God has provided us a faithful witness of what we need to follow to be prepared to serve under Him in His Kingdom. We must faithfully abide by what we are shown in His Word.
God promises He will be faithful (Deuteronomy 7:9). The apostle Paul declares God is faithful (I Corinthians 1:9). Both Jesus and Moses are declared faithful (Hebrews 3:1-2), and all of those leaders named in Hebrews 11 were faithful in their times of service. Now is our time to walk faithfully beside them. To be faithful is to be trustworthy, reliable, and responsible in our interactions with both God and man.
What must we do? What must we follow? The same basic things the heroes of faith did. It is easy to say we must keep God's commandments, which is certainly true. However, notice that those great leaders of the past are all mentioned for accomplishing some task more specific than keeping the commandments. Keeping the commandments is a general responsibility for all, and doing so is important in itself. Yet, each leader also achieved a specific responsibility: Abel made a sacrifice, Enoch walked with God, Noah built an ark, Abraham offered Isaac, Moses stood fast before Pharaoh, etc.
We need to understand our calling to be more specific and distinct than being “merely” one of a multitude in the church. How specific it is for each called individual is not yet known. Even so, being individually and personally called by the Father is awesome all by itself.
The apostle Paul shows in I Corinthians 12 that we must not think our calling is merely random, a coincidence. Such thinking glorifies neither God's genius nor His magnanimous generosity in stooping to call us. God is following a plan. He is creating a family team, and within His actions, nothing happens by chance, not even our calling:
For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ. For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. . . . But now God has set the members, each one of them, in the body just as He pleased. . . . Now you are the body of Christ, and members individually. And God has appointed these in the church: first apostles, second prophets, third teachers, after that miracles, then gifts of healings, helps, administrations, varieties of tongues. Are all apostles? Are all workers of miracles? Do all have gifts of healings? Do all speak with tongues? Do all interpret? But earnestly desire the best gifts. (I Corinthians 12:12-13, 18, 27-31)
God is expanding His Family, the church, and at the same time filling positions of responsibility to be faithfully performed by the elect. The church is called and formed as a body of people led by the Holy Spirit to do works representing God. There is undoubtedly some overlap in what the elect are required to achieve, but plainly, everyone does not perform exactly the same specific responsibilities.
No employer, be it a large corporation or an individual entrepreneur, looks for potential employees who cannot perform the available positions. No one, when first converted by God, is prepared to perform the tasks He has in mind for him, but each one has the potential to do just that if he will submit to the training God assigns. God is calling, training, and fitting us into the Body to follow Christ faithfully wherever He leads.
