Fitness
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.
In Hebrew, the word for hardness is "kosher". Interestingly enough, the word "kosher" also means "fitness", as from a workout in the gym. Yes -- it's a workout to serve the Lord in this world -- but God has called us to it!
These days, many people are working out intensely to beautify and strengthen their bodies. A lot of them are obsessed with appearance and youthfulness. It has virtually become a religion to be beautiful and/or "ripped", and people are willing to make serious sacrifices for the sake of their bodily condition.
Believers are called to a different kind of "workout" which can be equally or even more intense. Our "obsession" isn't with our bodies, but with our spirit. It is easy and "natural" to become caught up in the affairs of this life, even to adopt the worldly obsession with physical appearance. Yet our "workout" calls us to minimize the attention we give to worldly affairs, and to endure the hardness of spiritual warfare and service.
Are we aware of the reality of the eternal life which belongs to us, and of ALL its implications? Our life in this world is incredibly short, yet filled with tremendous opportunity for the Lord and our place in the world to come. If we want to please Him, (and we ought to think about why we would), we will make the most of our time, and work out with the greatest spiritual energy possible. That will involve saying no to worldly priorities and concentrating on spiritual ones.
If we have been chosen to be soldiers for God's great army this is no small thing! We will increasingly disentangle ourselves from prioritizing worldly pursuits, and be seeking first the things of the Kingdom of Heaven. When we do that we have two promises: earthly provision for all of our needs [Matthew 6:23], and treasure in Heaven [Luke 18:22]. Let us be the soldiers of God, not as conquerors, but as a massive caring and loving force for healing and lifting up.
Prayer: Lord, help us be more mindful of spiritual things than worldly things. Help us to know and believe that our bodies are Your temples, our things are gifts from You, and that soldiering for You is not the soldiering of this earth. Help us to be those who soldier for love, healing, and caring for our neighbors. AMEN
