 
Come to me, all who labor and are heavy laden, and I will give you rest.
Matt. 11:28 ESV
The gospel is the good news that God in Christ has come into the world and by his life, death, burial, and resurrection has conquered our greatest enemies: the world, the flesh, sin, death, and the devil. The gospel is the proclamation that our sins are forgiven and we are under condemnation no more.
This gospel calls forth a response of faith and repentance where upon we receive Christ’s righteousness and are granted right standing in the Father’s sight. Our response allows the Holy Spirit to transform our entire beings making us new creations in Christ.
The gospel is summarized by Jesus’ words, “I will give you.” “I,” salvation is found in the person, Jesus. “Will,” it is the Father’s desire to make this salvation available to anyone who comes. “Give,” the gospel is a gift, a gift of grace alone. “You,” salvation is about us and God’s love for us.
‘Come unto me,’ he says, ‘and I will give you.’ You say, ‘Lord, I cannot give you anything.’ He does not want anything. Come to Jesus, and he says, ‘I will give you.’ Not what you give to God, but what he gives to you, will be your salvation. ‘I will give you‘ — that is the gospel in four words.
Will you come and have it? It lies open before you.â€
