The gospel is not a set of propositions (Mk. 1:1), though it can and must be explained via propositions (1 Cor. 15:1-5). The gospel is not something we do, though it is something we respond to, and it leads us in obedience (Mk. 1:15; James 2:14-26). The gospel isn't about me, but it is for me. The gospel calls me to live in the now (Gal. 2:20) while looking to the future (1 Pet. 1:13).
