Don't think that believers never sin, and don't think we will get away with sin when we disobey or ignore God's commands.
If someone is all proud of the fact that they are getting away with sin without trials then maybe they are not born again and only think they are saved when they are headed for hell.
God said that He disciplines those whom He loves. Watch out, if we are a believer and are sinning or have unconfessed sin we can expect a spanking from God.
Hebrews 12:5-7 "…5 And you have forgotten the exhortation that addresses you as sons: “My son, do not take lightly the discipline of the Lord, and do not lose heart when He rebukes you. 6 For the Lord disciplines the one He loves, and He chastises every son He receives.” 7 Endure suffering as discipline; God is treating you as sons. For what son is not disciplined by his father?…"
Hebrews 12:8 "8 If you do not experience discipline like everyone else, then you are illegitimate children and not true sons."
