“And ye are complete in Him”.
When someone has truly beheld the Lamb of God, that is to say: when he has closed with the Lord Jesus Christ through faith – because seeing is believing – then he dwells in complete safety. Do you really know this? And do you believe it? That is why the apostle Paul says, not to just a few people, but to the whole Church of Christ: “And you are complete in Him.”
“But what about my sins?” Someone may think: minister, it is as if you know no sins. Ah, don’t talk of that! The Scripture says: “And ye are complete in Him.” And you will have to leave the Scripture as it is. “For upon all the glory shall be a defence” (Isa. 4:5). And “The Lord knoweth them that are His” (2 Tim. 2:19). He also knows what He has wrought in us through Christ. He will not forsake the works of His hands. “Being confident on this very thing, that He which hath begun a good work in you will perform it until the day of Jesus Christ” (Phil. 1:6).
“But what about my sins?” You may confess them. But they are forgiven. When someone prays: “Forgive us our debts, as we forgive our debtors”, then he has addressed God as “Father”, even though he did not use this name. He prays to a God and Father Who has reconciled us to Himself by Christ.
Your say: “Yes, but yet sins must be forgiven.” I have said to you: they are forgiven, namely them that are in Christ. “There is no condemnation to them which are in Christ Jesus” (Rom. 8:1). But you may confess them, in order it be given to you to enjoy again the love of the Father, the grace of the Son and the comfort of the Holy Spirit.
