Bible Study: Christians living in darkness?
John points out that it is possible for people to say they are in the light, yet actually live in darkness. Note the four “liars” here: (1) lying about fellowship, 1:6–7; (2) lying about our nature, saying that we have no sin, 1:8; (3) lying about our deeds, saying that we have not sinned, 1:10; and (4) lying about our obedience, saying that we have kept His commandments when we have not, 2:4–6.
Christians do sin, but this does not mean they must be saved all over again. Sin in the life of the believer breaks the fellowship but does not destroy the sonship. A true Christian is always accepted even if he is not acceptable. How does God provide for the sins of the saints? Through the heavenly ministry of Christ. We are saved from the penalty of sin by His death (Rom. 5:6–9), and we are saved daily from the power of sin by His life (Rom. 5:10). The word “advocate” means “one who pleads a case” and is the same Gk. word as “Comforter” in John 14:16. The Holy Spirit represents Christ to us on earth, and the Son represents us to God in heaven. His wounds testify that He died for us, and therefore God can forgive when we confess our sins. Read carefully Rom. 8:31–34. The word “confess” means “to say the same thing.” To confess sin means to say the same thing about it that God says. Keep in mind that Christians do not have to do penance, make sacrifices, or punish themselves when they have sinned. Every sin has already been taken care of at the cross. Does this give us license to sin? Of course not! The Christian who truly understands God’s provision for a life of holiness does not want to deliberately disobey God.
I felt the need to bring this to Heart Support as earlier in the day I replied to a young man’s question and thoughts on being a follower of Christ. He said he knows some Christians who have done horrible things, and I hope this can bring some clarity to that situation.
God’s Everlasting Love
31 What then shall we say to these things? If God is for us, who can be against us? 32 He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things? 33 Who shall bring any charge against God’s elect? It is God who justifies. 34 Who is to condemn? Christ Jesus is the one who died—more than that, who was raised—who is at the right hand of God, who indeed is interceding for us. 35 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? 36 As it is written,
“For your sake we are being killed all the day long;
we are regarded as sheep to be slaughtered.”
