The gospel is at the heart of our faith, and therefore central to the well being, not only of us, but of the world. Faith, hope, and love depend on it. No wonder then, when it can become such a point of contention. I commend N. T. Wright and his writings, along with other writers and teachers such as Scot McKnight and Craig Blomberg, and many others.
The gospel essentially is the Jesus revealed in scripture, and all the truth that surrounds him in his person, life, teaching, works, death and resurrection, ascension, and the promise of his return. 1 Corinthians 15 is a key passage, but actually Matthew, Mark, Luke and John are all accounts of the gospel. The good news in Jesus in which scripture is fulfilled.
It is imperative for us to hold on the gospel, not simply because of the life it promises after death, but also because of the life that is promised to us here and now. It is a life in God, one of no condemnation for those who are in Christ Jesus, because of Christ’s redemptive work of the cross, and the freeing activity of the Spirit (Romans 8). I find that we have to hold on to faith to get out of survival mode, though in spiritual warfare, simply to stand our ground is all that’s required (Ephesians 6:10-20). This is all about the gospel: the good news in Jesus, and holding on to that.
God wants us in Jesus to be more than conquerors, actually in him we already are (Romans 8), victorious (Revelation 2-3) in and through Jesus by the good news, regardless of what we face, or our past, as well as present. It may be in the midst of much weakness, and fallout. Nevertheless God wants the truth of that gospel in Jesus stamped onto our lives, so that it defines and centers us in all of life. The good news, by the way, is as big as all of life, if one reads the pages of scripture in full. It is no less than new creation, God making all things new. It is not a matter of hiding in a cave somewhere with bread and water. At the same time, though, it does involve a following with others of Christ in identification with him, which in this life can spell trouble, even death. But in the midst of that, we know from the good news that nothing in all creation can separate us from the love of God that is in Christ Jesus our Lord.
We need to pray and ask God to help us grasp and hold on to this good news in Jesus. That it might correct us where need be, and set us on the path of life, even of immortality, the eternal life and everlasting way in and through Jesus.
