When we go to the doctor and our vital signs are checked, we don't command our body to have a pulse, to perform respiration by breathing, or to have a 98.6º temperature. The signs of good health in the human body are natural manifestations of a body that is alive and well.
The same is true of the signs of spiritual health. True manifestations of spiritual vitality are not so much about what we do but about what Christ does in and through us. As the apostle Paul wrote, the life we now live in Christ is not our life, but Christ's life in us. Indeed, one of the purposes of Christ saving and indwelling numerous individuals on earth is so that all of us together might do greater works than He could have done as one person (John 14:12). Do we not have the freedom to yield to the presence of Christ (His Spirit) in us, or resist His work? Yes, and we can even perform good works in our own strength. But only that which is done by faith will last and be acknowledged (1 Corinthians 3:11-15).
Whatever you are doing for Christ, make sure your signs of life are signs of His life in you.
Whatever you are doing, in company or alone, do it all to the glory of God. Otherwise, it is unacceptable to God. Richard Baxter
