John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:

Galatians 2:16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.

1 Thessalonians 5:24 Faithful is he that calleth you, who also will do it.

2 Thessalonians 3:3-4 But the Lord is faithful, who shall stablish you, and keep you from evil. And we have confidence in the Lord touching you, that ye both do and will do the things which we command you.

Philippians 3:9 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:

It seems right to me that faithfulness and righteousness are in Christ Jesus and I only have access to them because I am in Christ. Apart from him I can do nothing. (I read that somewhere)

Yet when we speak we often assume the mantle of faithfulness without remembering where that mantle came from, to whom it belongs, and give glory to the One who allows us to wear it.

All this is possible because of the Cross of Christ, the single most impactful event in history, the game changer. It ended the law as the only means to righteousness, initiated faith as the standard for access to forgiveness, mercy, grace and a personal relationship with our Creator.
