If you have questions about the relationship between God’s sovereignty and our sharing of the gospel, I highly recommend J.I.Packer’s classic, Evangelism and the Sovereignty of God.
Below I have outlined J.I. Packer’s summary of the gospel message. Keep in mind, this is abridged. But it offers a basic outline of the Christian message. For more, read Packer’s Evangelism and the Sovereignty of God
I. The gospel is a message about God. It tells us who He is, what His character is, what His Standards are, and what He requires of us, His creatures . . .
II. The gospel is a message about sin. It tells us how we have fallen short of God’s standard; how we have become guilty, filthy, and helpless in sin, and now stand under the wrath of God. . . Not till we have learned our need to get right with God, and our inability to do so by any effort of our own, can we come to know the Christ who saves from sin.
a. Conviction of sin is essentially an awareness of a wrong relationship with God: not just with one’s neighbour . . .
b. Conviction of sin always includes conviction of sins: a sense of guilt for particular wrongs done in the sight of God . . .
c. Conviction of sin always includes conviction of sinfulness: a sense of one’s complete corruption and perversity in God’s sight, and one’s consequent need of what Ezekiel called a ‘new heart’ . . .
III. The gospel is a message about Christ – Christ the Son of God incarnate; Christ the Lamb of God, dying for sin; Christ the risen Lord; Christ the perfect Saviour.
a. We must not present the Person of Christ apart from His saving work.
b. We must not present the saving work of Christ apart from His Person.
IV. The gospel is a summons to faith and repentance.
a. The demand is for faith as well as repentance.
b. The demand is for repentance as well as faith.
