Some clarity on two important terms...
Some folks come to Christ (are saved) and then struggle with the notion of "I need to be getting better or I won't be saved". That is the basis for this clarification of terms. When you accept Jesus Christ as your savior, you are at that instant, justified before God. Justification is an instantaneous occurrence with the result being eternal life. It is based completely and solely upon Jesus' sacrifice on the cross (1 Pet. 2:24) and is received by faith alone (Eph. 2:8-9). No works are necessary whatsoever to obtain justification. Otherwise, it is not a gift (Rom. 6:23). Therefore, we are justified by faith (Romans 5:1).
So once you are justified, a great works begins in your life that is the process of sanctification. Sanctification involves the work of the person. But it is still God working in the believer to produce more of a godly character and life in the person who has already been justified (Phil. 2:13). Sanctification is not instantaneous because it is not the work of God alone. The process of sanctification is taking place from the time you are justified to the point you meet Jesus. The justified person is actively involved in submitting to God's will, resisting sin, seeking holiness, and working to be more godly (Gal. 5:22-23). Significantly, sanctification has no bearing on justification. That is, even if we don't live a perfect life, we are still justified.
The really exciting "next steps" that follow sanctification is glorification. That is the most amazing gift we can look forward to. We will one day be made like Jesus, perfect and free from sin. That will bring glory to Jesus and the Heavenly Father. That is glory!
