1Corinthians 15:1-4 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also you have received, and wherein you stand; By which also you are saved, if you keep in memory what I preached unto you, unless you have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures…
‘The gospel which I preached unto you, which also you have received, and wherein you stand.’ Man’s five-fold responsibility to the gospel: It must be studied, as preached by the apostles through the inspiration of the Holy Spirit (15:1; Mark 16:15). It must be received (15:1; John 1:12). It must be obeyed (15:1; Rom. 1:5; 6:17). It must be kept in memory – held fast (15:2; Heb. 3:6; 10:23; 12:14). It must be believed from the heart that will lead to obedience to every command and a life conformed to Christ’s image (15:2; Rom. 1:16; 10:9-10; John 3:16-20; 1Pet. 2:21-23).
‘By which also you are saved’ – Four main parts to the gospel of salvation: Death of Christ (15:3; 4:14-21; Rom. 5:6-10; Col. 1:20; Heb. 9:15); burial of Christ (15:4; Matt. 26:12; John 12:7; Rom. 6:4; Col. 2:12); resurrection of Christ (15:4, 12; Rom. 14:9; 2Cor. 5:15; 1Thess. 4:14); manifestation of Christ after the resurrection (15:5-8).
