2 Timothy 2:3 - You therefore must endure hardship, as a good soldier of Christ Jesus. -- World English
Every Christian as a soldier of Jesus is in a war. His warfare is, however, spiritual, not with physical weapons often associated with being a soldier. A good soldier obeys his commanding officer. Unlike the hatred that often prevails with soldiers fighting carnal battles, Jesus tells his soldiers to love their human enemies in this world, and to do good to those who hate them.
The Christian has several things he must battle: 1) sin and evil in his own flesh, 2) allurements of the world to sin and evil, and (3) the deceptive attacks of Satan and his demons that would lead us away from what is right to what is sinful and evil in God's sight. The common element in all three is sin and evil. What the world considers to be good, may, in fact, be evil from God's standpoint, so the good soldier of Christ should endeavor to come to know what is evil according to God's standards, not by the world's standards.
As a soldier in an army of the world must believe and have faith in the cause for which he is fighting, so the soldier of Jesus must be convinced in his own heart of the righteousness of his cause. This involves the heart loyalty of the Christian soldier in submission to Jesus and his God.
One of the commands of our commanding officer is to let our light shine in the world and to preach the Gospel, the Good News, to others. To let our light shine does not mean to flaunt what we might deem to our own righteous acts before others, or to condemn others, but rather to simply and humble be obedient to Jesus' commands as we are able, so that others may see our faith and love for what is right in Christ. The goal is let Christ be seen in us, not that others may see our own righteousness. To preach the Good News is to present the truth from the Bible about Christ to the best of our ability and knowledge.
We are assured, however, that obedience to Christ will bring persecution. Thus, the need for endurance while facing the opposition of a world that does not love or care for God's righteousness. -- Ronald R. Day

Being a soldier of Christ means have heart loyalty to Jesus, but if our heart is actually in submission to someone else other than Jesus and his God, we fall short of true obedience to the one whom we profess as our "commanding officer." There have been and still are many who would seek to bind us to themselves, or to some man, or group of man, other than Jesus and his apostles, so as to claim all must be obedient to and/or in agreement with what such men may say. Some even make such an agreement as a basis for salvation. I do not believe that our Lord Jesus approves of such a bondage to leaders.
