Vs. 21 - And although you were formerly alienated and hostile in mind, engaged in evil deeds,
- Verses 21 & 22 are an expanded explanation of verse 20 (In which ‘He reconciles all things’). Verses 21 & 22 are a pretty decent definition of 'reconciliation'. Note: vs. 21 is a good definition of an enemy, especially an enemy of God and Christ (see Eph. 2:2,3). These verses present a simple equation: we were alienated (enemies); He has reconciled us (turned us into friends).
Evil deeds are not the reason for us being enemies of the Holy God. They are the symptom. 'Actions speak louder than words' is a good representation in that our deeds show what our nature is.
- see: "God demonstrates his own love for us, in that while we were yet sinners, Christ died for us." Rom. 5:8; Rom. 5:14-21.
- "in order to" - Now we will see the purpose, or reason for Christ's sacrifice. His death on the cross was so we may be presented 'holy and blameless and beyond reproach' (See: Jude 23, 24). Since 'God is light, and there is no darkness in Him' (1 John 1:5) we can have no darkness at all in us to be in His presence (see: Eph. 1:4, 5:27).
Only if we are as pure as Christ can we be with God. Think about that for a bit. Are you perfectly pure? If you say, "Yes" you are deluding yourself into thinking you are much, much better than you really are.
Now we need to behave differently. Go back to chapter 1:9-12 - see the list of characteristics: filled with knowledge, get wisdom and understanding, strengthened, walk worthy, please Him, bear fruit, steadfastness (endurance), and patience.
Christ's sacrifice HAD to be physical as well as spiritual. Sin came into the human race by a physical and spiritual actions - Adam and Eve decided to disobey, and did disobey - both spiritual and physical rebellion. We believe they were led by Satan, the original rebel. He lusted to be equal to God. We cannot see any direct evidence of that rebellion. We see 'circumstantial evidence' - sin in the world, a decaying and destructive world. The sin was a physical sin, the restitution, reconciliation must also be physical. Just as we must physically acknowledge Christ as Savior before men (see Rom. 10:9-10).
Why confess Jesus? (Other than the command...) If you and I merely think about Jesus, and make a mental acceptance, then it is easy for us to 'conveniently' dis-acknowledge our belief ("I really didn't accept Him as Savior..."). If we confess Him out loud, before witnesses, it is much more difficult to change our minds about our commitment. We can be held accountable by our fellow man. It is easier to rationalize misbehavior when it is only in our mind. To have it out in public, a renouncing, takes a major step.
- I do not believe this verse deals with loss of salvation, but instead deals with loss of fellowship due to sin and wavering. It is speaking of a Christian who does not appropriate the cleansing qualities available to him through the Holy Spirit (1 John 1:9). See also: 1 Cor. 3:11-15.
At the judgement seat of Christ each Christian will be presented to Christ, purged of unconfessed sin and then presented pure and blameless to to the Father. Loss of faith and loss of hope, as a result of straying from the true gospel tends to break us down. We no longer live boldly for Christ, but blunder as if in darkness. If you do not remain faithful, then you will break away, to live and act as if not reconciled. We must live differently than when we were unsaved.
