No One Man Armies
A Christian that forsakes the fellowship of the believers (gathering for prayer, the taught Word, sharing the Word and worship) is like a soldier who lays down his weapon and body armor and wanders off from his company or platoon unconcerned he/she has crossed enemy lines and unaware there is even a war.
"Put on the full armor of God so that you can take your stand against the devil's schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand." (Ephesians 6:11-13)
The most significant phrase in this passage is "our struggle"! Together Christians are in a struggle and the only way to win is to stand together, pray together, love together, live together, learn the Word together. There are no "One Man Armies" in the Kingdom of God.
"It is the Church that overcomes. Spiritual warfare is the task of the Church, not the individual. We take Ephesians 6 for ourselves individually--and I do not say there is no individual application of the armour--but the individual by himself cannot 'put on the whole armour of God' any more than he can comprehend alone the measure of the love of Christ. Seen in the light of the rest of Ephesians, it is, I feel sure, armour for the Body--a special piece for each member. For to try and fight this warfare alone is to invite trouble from an enemy who has no fear of the individual, but who dreads the one Body."—Watchman Nee
