2 Corinthians 5:18-20 "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 people’s sins against them. And he has committed to us the message of reconciliation. We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God."
God has made you an ambassador for Him, and He's given you the privilege of announcing the good news of reconciliation. Don't wonder why He uses you today; just do what He calls you to do. Implore others to be reconciled to Him.
