The gospel contains nothing about baptism, church membership or attendance, tithing, sacraments or rituals, diet or clothing….The gospel is all about what Christ has done. It says nothing about what Christ must yet do, because the work of our redemption is finished. “Christ died for our sins” (1 Cor:15:3). His death on the cross is in the past, never to be repeated. Nor does the gospel say anything about what we must do, because we can do nothing (Ti 3:5; Eph:2:8-9). Instead…the gospel requires faith. It is the power of God unto salvation to those who believe (Rom:4:5; John:3:26). The gospel is a two-edged sword. It declares, “He that believeth on the Son hath everlasting life.” The same verse also says, “He that believeth not the Son shall not see life; but the wrath of God abideth on him” (Jn:3:36).
