For the love of Christ controls us, having concluded this, that One died for all, therefore all died; and He died for all, that they who live should no longer live for themselves, but for Him who died and rose again on their behalf...
Therefore if any man is in Christ, he is a new creature;
the old things passed away; behold, new things have come.
Now all these things are from God who reconciled us to Himself through Christ, and gave us the ministry of reconciliation, namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation.
Therefore, we are ambassadors for Christ, as though God were entreating through us; we beg you on behalf of Christ, be reconciled to God. He made Him who knew no sin to be sin on our behalf, that we may become the righteousness of God in Him.
2 Corinthians 5: 14-21
My hope lives not because I am not a sinner, but because I am a sinner for whom Christ died;
my trust is not that I am holy, but that being unholy, He is my righteousness.
My faith rests not upon what I am, or shall be, or feel, or know, but in what Christ is, in what He has done, and in what He is doing now for me.
Charles Haddon Spurgeon
