Titus 3:9 (NKJV)
Over the years I have been a member of a few health clubs and I have also owned some exercise equipment. One thing that I did before getting involved in a health club and using any exercise equipment was to familiarize myself with what exercises I could do and the proper way to do them. But, I have noticed over the years that there are some people in health clubs, and who exercise on their own, who do not really know how to exercise correctly so that what they are doing is not helping them, in fact what they are doing is just wasted motion. While they are doing something, what they are doing will have no real, lasting benefit.
God gave us His Word to help us learn His will and to see how to live the kind of life that pleases Him. God knows the challenges we face in life and His Word gives us the guidelines we need to know what to do in every situation. The Holy Spirit will direct us as to how we can do the things we need to do and help us as we step out in faith to act on God's Word. But, if we are putting our focus on and efforts into something that God has not said in His Word then we will not have the results in our life that God has promised and we are seeking. If what we do is not based on the Bible it is just wasted motion.
The Apostle Paul talked about avoiding some things because they were unprofitable and useless. Too often Christians are doing things that may seem nice and look good, but they bring no real benefits because these things are not based on the Bible. People are sometimes taught to do certain things in a certain way as a method for success, but if these things are not in agreement with the Bible they are unprofitable and useless. We need to get into God's Word to have a thorough understanding of it so that we are sure what we are doing is in line with the Word and not just wasted motion.
