When I started Physical Therapy I was shocked when they told me that my back muscles were like mash, reduced to pulp, fleshy tissue. Due to the fact that I have had several fusions, I'm not allowed to bend or do any lifting at this time, so all my exercising and strengthening of my back muscles have to come from exercising my legs and abdomen. Believe it or not, after working out these muscles, I do feel it in my back. All the leg stretches, lifts, presses and so on, actually targets my back muscles as well. I feel great after a workout. I find it is much easier to start my day off with my leg stretches before getting out of bed. It works out the aches and pains and I can move much easier. Then if I hit the treadmill first thing after I wash my face and brush my teeth, I'm sure to have a much better day. But if I don't exercise on any given day, I always feel sluggish and ache all over. I don't want to move because it just hurts to much. All day I have aches and pains and I'm a miserable person.
I was thinking about this and it is no different in our spiritual life. If we don't exercise daily by Praying, our spiritual muscles will turn to mash, be reduced to pulp. We will become sluggish in our walk with Him. Our spirit will begin to ache and we won't want to move and we will become miserable people. We won't have the strength to stand against the fiery darts that come against us. We won't have the power or strength to fight off temptations, worldly lust and desires when they come our way. Our attitudes will not be Godly attitudes. We become impatient, hateful, short tempered, lustful, easily offended, lackadaisical, unthankful, unholy, disrespectful, etc. That's why Paul said in 1st Corinthians 15:31; "I die daily", meaning through prayer, he dies out to his flesh, his will and desires and gives way to the will of God. He is strengthening his spiritual muscles so that when things come against him he will have the strength to stand and not fall to temptation.
As much as we need to exercise daily physically, we also need to exercise daily spiritually. I was determined to grow stronger physically so that I could stand and walk on my own without the assistance of a walker or cane. I'm determined to build my muscles up in my back as well. It will take a lot of hard work and exercise but I have to work at it to succeed. I'm just as determined to stand one day and say as Paul did in 2 Timothy 4:7 I have fought a good fight; I have finished my course; I have kept the faith." I must die daily to do so. I must exercise my spiritual muscles and keep them strong through prayer and the Word of God.
