Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? (Galatians 3:3)
Most of us learned justification as the beginning of our relationship with God, saying “we trusted Jesus alone for our salvation; we were declared “righteous” in God’s sight, given the very righteousness of Jesus as a gift.”
But what if justification by faith has a beginning, middle, and ending? Meaning this: when we initially believe that Jesus is Lord and Savior and receive Him by faith we are in, what Douglas Moo, calls, “the initial phase of justification.” But our justification is proved true as we walk out our life by faith, all the way to our death.
This why Galatians is such an important book. The Galatians began well — they trusted Christ alone for their salvation. But then false teachers moved in and began teaching that you must have faith in Jesus and obey the Law for justification. Jesus plus Obedience to the Written Code. The Judaizers were condemned for their teaching, and the Galatians were in danger of becoming like them. They were in great danger of proving their initial faith was not a saving faith if they embraced the law, typified in embracing circumcision.
This is also the point that Paul is making when he rebukes Peter, described in ch. 2. When Peter sides with the Judaizers and begins distancing himself from non-Jewish Christians Paul rebukes him by explaining justification. Look at what Paul says, “we also have believed in Christ Jesus, in order TO BE justified by faith in Christ and not by works of the law, because by works of the law no one will be justified” (2:16). “We have believed, in order to be justified by faith.
Here even an apostle of Christ is in danger because he has stopped living by faith and has taken up the law. (We know that Peter repented of this error, and that Peter was present to settle the matter at the Jerusalem council in Acts 15). But do you see? Justification is by faith alone in Christ alone, but it is not just our beginning — our justification is confirmed as we continue to live by faith, forsaking sin AND the law.
Therefore we can conclude that there are two ways to show that an initial faith in Christ was not a saving faith at all. One is to fall away from the faith, rejecting Christ after once “accepting” Him. And the other is to fall from grace: to pursue your life with God by works and not by faith, looking to the Law, and, your obedience of it, to give you assurance, security, and blessings in this life and the next. So to summarize, we can begin with God and prove our belief to be false belief by falling away from the faith and going back to living for self, or falling away from grace and living for God by the law. They both end in condemnation.
Justification is by faith alone, a faith that looks to Christ for salvation and present life. That is why FAITH is so important AFTER our initial belief. Much more is at stake RIGHT NOW for all believers. Salvation is not beginning with faith and then being inoculated for the rest of your life no matter how you live. Salvation is secured by faith in Christ from FIRST to LAST (Romans 1:17). We can’t trust Jesus for a relationship with God and then not trust God with our life afterwards.
So how do you know if you are a living a life of faith after beginning by faith? Look at the fruit of your life. If the fruit of your life is fear then you are not living by faith. If what is coming out of you is the works of the flesh: jealousy, envy, strife, hatreds, sexual immorality, impurity and other things like these — then you can know that you are not living by faith. But if the fruit of your life is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control as a whole, then you can know that you are living by faith.
These are not emotions. They are motives. If you are motivated by fear (If I don’t get life right then I won’t get the life I want) then you can must assuredly know that your initial faith is a of little use.. You are trusting the law, heaping condemnation on yourself.
