Paul, the aged apostle of Jesus Christ recognized he was nearing the end of his earthly journey. Just as Jesus commissioned His disciples to “…go ye into all the world and preach the gospel to every creature,” Paul fervently wished to pass the vital torch of the truth to Timothy, his “son in the gospel.” He admonishes Timothy to be “a good soldier of Jesus Christ” and gives him certain perimeters for guidance.
First, he tells him to “be strong in the grace that is in Christ Jesus.” Grace is God’s favor, anointing (divine enablement), protection and provision. As God told Paul, His grace is all sufficient for all things.
Secondly, as a recipient of this great saving gospel, Paul tells Timothy he must teach others also. (If each one won one and each one won, won one we could reach the entire world in one generation).
Then Paul reminds Timothy that he must “endure hardship.” Soldiers lead a life of sacrifice and often must deprive themselves of ordinary creature comforts. He reminds Timothy not to “entangle himself in the affairs of this life.” Jesus also warned us not to be overcome by the cares and anxieties of life.
Lastly, Paul reveals the principle motive of a true soldier of Jesus Christ: to please the Lord that called him to be a soldier. This old song expresses well the Christian soldier’s determination: “It's a battlefield, brother, not a recreation room; it's a fight and not a game. Run if you want to, run if you will, but I came here to stay.”
