For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes.” (v.16)
After a short greeting (v.1-7) and an explanation of his desire to have visited them sooner (v.13), Paul sets the tone of his letter to the Romans here in verse 16 concerning “the gospel” (good news) of Christ. The “good news” he presents to them without shame is, “the gospel of Christ contains the power of God to salvation for everyone who believes.”
The key words being “everyone who believes.” Paul’s message of grace is so simple, that this is where many are vulnerable to error. We begin to think there is something else we should do, some works we should perform.
Paul goes on to tell us in verse 17 that, “the righteousness of God is revealed from faith to faith” and that “the just should live by faith.” Therefore, faith is not only the starting point of salvation, but also the staying power as well. Meaning, once we as Christians have received Christ by faith, we walk through this life with Him in faith as well.
The Christian life is not without “trials and tribulations.” But as Paul reminded the Galatians, “Having begun (your walk) in the Spirit, are you now perfected in your own flesh (knowledge)?” No! “For those who are in the flesh can not please God” (Romans 8:8)
Therefore, Paul would say to us, “Walk ye in Him” (Colossians 2:6)
