The Lord has called all believers to join in His work: 

"... 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 and gave us the ministry of reconciliation: that God was reconciling the world to himself in Christ, not counting men's sins against them.  And he has committed to us the message of reconciliation."  2 Corinthians 5:17-19
