The concept of stepping expresses following in the tracks of another. It is derived from a word meaning a row, a line, or a “rank of soldiers.” Thus, it carries the meaning of walking in a file or marching in step.
Following this foundational meaning, in Acts 21:24, when Paul returned to Jerusalem, James spoke to him about the rumors that had reached the assembly concerning him. They were informed by Jews of Asia that Paul was teaching the Jews to forsake Moses and no longer circumcise their children. So that Paul could prove to the assembly in Jerusalem that he stepped according to the Law—for there were many among them who were zealous for the law—James encouraged him to pay the expenses of a few men who were under a Nazarite vow so they could fulfill their vow.
Similarly, in Romans chapter 4, Paul explains that righteousness accounted by faith is not just for the seed of Abraham. Abraham was saved when he was uncircumcised. The sign of circumcision was given as a seal of the righteousness of faith, that he might be the father of all who believe; both circumcised and uncircumcised. This happiness of the righteousness of faith is therefore to all who step in the same footsteps of faith (Romans 4:12).
Building upon this, in Christ Jesus, neither circumcision nor uncircumcision avails, but the new creation. This is the new creation that God made when He raised Christ from the dead, in which Christ is the head and the Church the body (Ephesians 1:22-23). Peace and mercy are upon those who step according to this standard (Galatians 6:13).
In the context of maturity, those who are mature should have the same mind as Paul, who desired to be found not having his own righteousness, which is based upon law, but the righteousness through faith in Christ Jesus. This is a righteousness that comes from God on the basis of faith. With this mindset, those who desire to mature press on, on the basis of the high calling in Christ Jesus. Thus, to the degree we have matured, let us step by the same standard (Philippians 3:16).
In summary, walking is a general way we conduct our lives. Stepping is carefully following a track that has already been laid. Since we live by the Spirit, we should also take each step by the Spirit (Galatians 5:25). Thus, each of our steps concerning our conduct is taken with consideration and focus as we press on towards maturity in Christ. We press on because of the high calling we have in Christ, not seeking our own righteousness, but abiding in the righteousness we have in Christ.
