How many times is the word 'reconciliation' mentioned in the New Testament?

Answer 1

Three times in the King James and New King James; four times in the NIV. The references are:

Romans 5:11 - And not only that, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received the reconciliation. [NKJV]

Romans 11:15 - For if their rejection is the reconciliation of the world, what will their acceptance be but life from the dead? (NIV)

2 Corinthians 5:18, 19 - Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation. [NKJV]
