“The reminder of what we have become by grace is a constant defence against slipping back into what were by nature.” (Ferguson, Sinclair. The Christian Life. (Carlisle, PA: Banner of Truth, 2006), 114)
The Gospel of Jesus Christ is not merely the door by which we enter the Christian life. It is much more than that. It is the house within which we dwell as Christians. As Ferguson points out in his excellent work, The Christian Life, a regular reminder of the Gospel is the best defense against slipping back into old sinful habits. The Gospel needs to be preached weekly from the pulpit in our churches, returned to often in our small group Bible studies, and regularly remembered in our daily lives.
In his first epistle to the Corinthian church, Paul is addressing several sins that have corrupted the local congregation. His chief remedy is to remind the church of the Gospel of Jesus Christ that he preached to them.
“I give thanks to my God always for you because of the grace of God that was given you in Christ Jesus” (1:4)
“For Christ did not send me to baptize but to preach the gospel” (1:17)
“For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.” (1:18)
“we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.” (1:23-24)
“And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.” (6:11)
“You are not your own, for you were bought with a price. So glorify God in your body.” (6:19-20)
“Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, and by which you are being saved, if you hold fast to the word I preached to you – unless you believed in vain.” (15:1-2)
“For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas, then to the twelve.” (15:3-5)
Preach the Gospel to yourself daily.
