After we are saved from sin, we are commanded, “Go, and sin no more” (John 8:11).
We are commanded to live soberly, righteously and godly in this present world (Titus 2:12) and warned that without holiness no one shall see the Lord (Hebrews 12:14).
We must present ourselves as holy unto God (Romans 12:1), cleanse ourselves from all filthiness of the flesh and spirit (II Corinthians 7:1), and separate ourselves from all worldliness (James 4:4).
If the righteous scarcely be saved, where shall the ungodly and the sinner appear? (I Peter 4:18).
