2 Co 5:18 ...God, who has reconciled us to Himself through Jesus Christ...
Many are painfully aware of their spiritual separation from God because of their sins. But many of them are also woefully ignorant about the way to be reconciled to God.
Some opt for religious activities to be reconciled to God. Others attempt to be reconciled to God through their good works. Still, others go for it through personal sacrifices.
My friend, the way to be reconciled to God is "through Jesus Christ."
He died for our sins and rose from the dead. That if we repent and trust in Him and what He did on the cross, we will be reconciled to God just as the Corinthians here in the verse we are considering.
Come to Christ. Turn to Him. Trust and rely on Him and what He did on the cross for your salvation. And you will be reconciled to God.
