John Piper is right on in this sermon. John says NEVER NEVER NEVER NEVER NEVER think of the Gospel as a way to get saved and think you can leave it behind and do something else to get strong.
The Gospel is…
We are more sinful and weak than we ever dared to admit and…
We are more loved and accepted than we ever dared to hope.
1 Thessalonians 5
1Now, brothers, about times and dates we do not need to write to you, 2for you know very well that the day of the Lord will come like a thief in the night. 3While people are saying, “Peace and safety,” destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
4But you, brothers, are not in darkness so that this day should surprise you like a thief. 5You are all sons of the light and sons of the day. We do not belong to the night or to the darkness. 6So then, let us not be like others, who are asleep, but let us be alert and self-controlled. 7For those who sleep, sleep at night, and those who get drunk, get drunk at night. 8But since we belong to the day, let us be self-controlled, putting on faith and love as a breastplate, and the hope of salvation as a helmet. 9For God did not appoint us to suffer wrath but to receive salvation through our Lord Jesus Christ. 10He died for us so that, whether we are awake or asleep, we may live together with him. 11Therefore encourage one another and build each other up, just as in fact you are doing.
