God created the world good, but humanity plunged into sin. We deserve everlasting abandonment and punishment.
But the “Word became flesh and dwelled among us”, experienced suffering with humanity, and paid the price on the cross for humanity’s sin. Showing he was the true Son of God, and showing that his work was finished and his words were true, Jesus Christ rose from the dead. He even ate fish with his disciples.
Now, anyone who stops trusting in themselves or false gods, and instead trusts in Christ alone, is given the free and immediately-starting gift of eternal life, forgiveness, justification, rebirth, the indwelling Holy Spirit.
Their life begins anew and God transforms them to love their enemies and to forgive as they have been forgiven. Now they are to go throughout all the world declaring the authority and work of Jesus Christ, awaiting his return.
