Only One Gospel

"We must be careful that we do not modify the gospel to suit various age groups. There is no such thing as a special gospel for the young, a special gospel for the middle-aged, and a special gospel for the aged. There is only one gospel, and we must always be careful not to tamper and tinker with the gospel as a result of recognizing these age distinctions. At the same time, there is a difference in applying this one and only gospel to the different age groups; but it is a difference which has reference only to method and procedure."

D. Martyn Lloyd-Jones

The Essence of Sin

"The essence of sin is to fail to glorify God. Man was made to glorify God - 'Man's chief end', the Shorter Catechism tells us, 'is to glorify God and to enjoy Him for ever'. And, you see, if we only defined sin as the failure to do that, we would see how everybody is a sinner, and we would see how the most respectable people can sometimes be the most terrible sinners. They have never been guilty of certain particular sins - of course not, but they do not glorify God; they glorify themselves. So many people say, 'I cannot feel that I am a sinner, I have never felt it'. That is because they are thinking in terms of sins; if only they saw that sin is really just a failure to glorify God with the whole of their being all the time, they would see that they are terrible sinners."
