How does God see you?

The Question: What is a reference for God seeing us 'through' Christ vis - 2 Sam 22:@5? i.e. Christ's righteousness as ours.

On the surface this seems like an easy question but it is also one that has been and will continue to be embroiled in controversy over the years. The reason for this is because the question is one that touches on one of the cornerstone statements of faith, namely 'justification by faith' (JBF).

Let's briefly examine why this is such a central aspect to Christianity. The cross is the central point, the pivotal saving point; JBF is also at this point. To distort JBF is to distort salvation and
faith is the instrument of salvation.
a) Faith in Jesus Christ alone as presented in the gospels therefore we preach Christ in a JBF kind of way because there is no other way
b) Faith arises from the Holy Spirit in rebirth and so is evidence of regeneration, but not merely evidence, it is the means and instrument which we we grasp Christ and his benefits
c) Its effective in Jesus in dealing with sin on the cross, our righteous actions can’t acquit us. He totally bore sin and justifies the ungodly
d) Faith is ‘reckoned’ for righteousness (account something). Faith in Jesus Christ that is counted as righteous. Whose righteousness is it? God’s given by JC
e) Faith alone makes Jesus Christ Lord, but this makes faith never alone
f) Only faith makes Jesus Christ Lord, this is truly exalting Jesus
g) Faith alone gives us access to God (Ro 5:1-11): constitutes the ongoing basis of access to God.

Having seen the importance and centrality of justification by faith let's turn to the Scripture. There are many references that answer the initial question:

Rom 3:22

The righteousness of God through faith in/of Jesus Christ for all who believe

Rom 6

The whole idea of being united to Christ

I cannot stress just how important the idea of union with Christ is. Martin Luther in his famous treatise "On the freedom of a Christian" was expounding on what it means for us to be united with such a wonderful bride in Jesus. Listen and rejoice in Luther's words:

It is impossible now that her sins should destroy her, since they have been laid
upon Christ and swallowed up in Him, and since she has in her Husband Christ a
righteousness which she may claim as her own, and which she can set up with
confidence against all her sins, against death and hell

Union with Christ gives the Christian great assurance. Being united with Christ gives victory over sin and death. As Luther goes on to say;

Our sins are unable to destroy us, Christ the righteous husband, takes on
the needy and impious harlot and gives her all his good things

Those who belong to Christ have died with him to sin and death, and now live to God and to righteousness.

Rom 13:14

But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.

Gal 3:27

For as many of you as were baptised into Christ have put on Christ.

It seems clear to me that when God sees us his perspective is that we are clothed in the righteousness of Christ. And as a result of this he declares us to be righteous.

Is this how God sees you - if not, probably time to do something about it? Time to get some God given faith!!
