You therefore must endure hardship as a good soldier of Jesus Christ. No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier. And also if anyone competes in athletics, he is not crowned unless he competes according to the rules.

2 Timothy 2:3-5
In all armies of the world, soldiers are subjected to a very strong training. No one who has gone through the military can say no penalties suffered in his career. If that is the natural plane, in the spiritual world the matter is not very different. A soldier of Jesus Christ also will suffer penalties, not only during training, but every day. Military training is just child’s play facing the reality of war. The soldier of Jesus Christ lives daily in a war.
The Dominican singer Juan Luis Guerra composed a song titled “Soldier.” In one of its verses the song says: “I’m a soldier, a soldier of Christ, well armed and protected, I bring a double-edged sword, for His word carry with me.” The song continues: “I am a soldier; I fight in cities against darkness and powers. I am a soldier of testimony, I trample on snakes and I tie demons in the name of Christ.” Finally, the song says: “I am a soldier, a militia man on the breastplate of righteousness. I am a soldier, I am an anointed one, I break ties from the enemy in the name of Christ.”
Every soldier, once trained, he is going out to battle properly equipped with everything he needs to fight. The soldier of Jesus Christ is no exception. Ephesians 6:11 says: Put on the whole armor of God, that you may be able to stand against the wiles of the devil. The armor of God is the equipment of every soldier of Christ, it continues Ephesians 6:13: Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.
The soldier of Jesus Christ does not fight against flesh and blood but against an army of evil spirits. Ephesians 6:12 says: For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. Therefore, our weapons must be suitable for our struggle. In this sense, it says 2 Corinthians 10:3-4: For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds.
A soldier of Jesus Christ, as one of any army on earth has been given the power and authority concerning his military investiture, Jesus Christ, our commander in chief says in Luke 10:19: Behold, I give you the authority to trample on serpents and scorpions, and over all the power of the enemy, and nothing shall by any means hurt you. Then we are ready to fight because we have been trained, equipped and with power for battle, to face the enemy, which has been fully identified.
No matter we receive wounds during battles every day. We must remain loyal to who has recruited us as soldiers. We do not become entangled with the things of the enemy, but take care to be always stuck to our discipline as soldiers of Jesus Christ. Do not be a quitter, because they are deserters to whom is applied the death penalty. God bless you.
