I have found that breaking it into four parts not only helps me have a clear understanding, but makes it easier to share. The four parts are as follows:
G, M, C, R: God, Man, Christ, Response.
God: Oftentimes when we are thinking of sharing the gospel, we start with man’s sin, but where we really need to start with God. The problem of man’s sin is really only a problem if there is a holy and just God whom we sin against.
God is a holy God, who created the whole world and everything in the world. He created man, Adam and Eve, in his image, to be in a perfect relationship with God, having him as their sovereign creator and ruler, living under his rule, and having dominion over the earth that God created.
Man: Though created in God’s image to live under his loving rule, man rejected God. Adam and Eve believed the lies of Satan and wanted to rule themselves. In making this choice, they rebelled against God, bringing sin into the world and with it, the punishment of death that we all now deserve.
Christ: But, although we deserved death for our willful rebellion against the sovereign ruler of the universe, God in his mercy sent Jesus Christ, fully God, fully human, to live the perfect, sinless, obedient life that we could not live, and to offer himself up as a perfect sacrifice on our behalf, dying the death that we deserved for our rebellion. We know his sacrifice was fully accepted by God because on the third day he rose again, showing that death had been defeated.
Now we could just leave it here, but that is not the whole gospel. The gospel requires a response, which is our fourth point.
Response: Our response is to repent, that is, to turn from our wickedness and from trying to earn God’s forgiveness, and to put our faith and trust in Christ, believing that what he has done is sufficient for us to be reconciled to a holy and righteous God.
This is a very simple explanation of the gospel that can be shared in a few minutes. However, we would be misrepresenting the gospel if we were to leave out any one of these elements.
2) The second point we briefly want to touch on is, “Why am I sharing it?”
Matthew 28:18-20 is often referred to as the great commission. It is here that we have Jesus telling his disciples to go and make disciples of all nations, baptising them in the name of the Father, Son and Holy Spirit.
So, the question arises, “Who is a disciple?” or at least, “How does one become a disciple?” The simple answer is, by responding to this gospel that I have outlined in the first point. We share the gospel, we evangelize, in order to make disciples.
