For Christ’s love compels us, because we are convinced that one died for all, and therefore all died. And he died for all, that those who live should no longer live for themselves but for him who died for them and was raised again. So from now on we regard no one from a worldly point of view. Though we once regarded Christ in this way, we do so no longer. Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come! All this is from God, who reconciled us to himself through Christ. (2 Corinthians 5:14–18, NIV 1984).
My Musings – As a wise former Pastor of mine once commented, whenever you see the word “therefore,” you need to look to see what it is there for. The old (creation) has gone, the new (creation) has come. But only if one is “in” Christ Jesus. So we look to what came before to determine the therefore. Being “in” Christ is only possible because “one [Christ] died for all.” That we should no longer live for ourselves (“the old has gone“), but for Him who died and was raised (“the new has come“).
My Advice – “The new has come.” Available for all, but not automatic for all. One has to be “in” Christ Jesus. One must be “born again” as a new creation.
