2 Corinthians 5:18
Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation,…
Through Jesus Christ we have been reconciled to God. Reconciled means to restore relationship, and to make an exchange. He took our sin on the cross so that we could receive His righteousness. It is this righteousness (right standing with God) that gives us the right to all that we have in Christ. We now have a ministry to go and reconcile others to God.
In the verse that follows the above scripture it goes on to tell us that God was in Christ Jesus reconciling the world to Himself, no longer counting their sins against them. To reconcile others to Christ we need to let people know that God has already dealt with their sins through the cross. It is not all their sins that is now separating them from God, but in fact in John 16:8-9 Jesus tells us that there is one sin that is hindering man from receiving the reconciliation that God has provided, and that is the sin of not putting their faith in Jesus Christ.
In the eyes of God the world has been reconciled to Him for there is nothing more that He needs to do. They simply need to turn to God and put their faith in Him, receiving Jesus as the Lord of their life. Time for the church to go and shine their light to those in darkness and to let them know God is waiting on them to receive them back into fellowship with Him.
