Jesus’ teachings and actions, recorded in the four accounts of Matthew, Mark, Luke, and John, model the kind of life to which we should all aspire, defined by love, grace, and compassion. However, more than that, Jesus urged people to turn away from sin in their lives and to renew their relationship with God. For us on our own this is an impossible feat. We were all created to be in a loving relationship with God, but our relationship with Him was broken because of sin.
The result of that broken relationship is emptiness, restlessness, and an unfulfilled longing within each of us. But, through accepting Jesus as Lord and Savior, believing that He died and resurrected to redeem us from sin, we can receive His righteousness and be renewed in our relationship with God, being counted as children of God. This is the gospel: that God loved the world so much that He sent His only son to live a perfect life and to die sacrificially, bearing the full weight of our sin, rescuing us from an eternity separated from God and freely offering the opportunity to live rightly with God forever.
