2 Corinthians 5:18 All this is from God, who reconciled us to himself through Christ, and has given us the ministry of reconciliation; 19 that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting the message of reconciliation to us.
Paul has been writing about Christians being made new in Jesus Christ. Instead of being trapped in sin forever, separating us from a holy God, the forgiveness we receive through Christ cleanses us from sin and brings us near (reconciles us) to God. And now that we ourselves are Christians God “has given us the ministry of reconciliation”.
The Lord Jesus (then and now) uses everyday believers to draw people to himself.
When I think of my own faith journey I recall several people the Lord used to draw me close to him, starting when I was a child into adulthood. I’m so grateful for all of them and pray the Lord uses me to connect others to Jesus.
