“I do not believe that any man can preach the gospel who does not preach the law”-Charles Spurgeon
If we are to help people find their way to Jesus and Heaven, than we need to realize that some people need a reason to go that route. For most of us, one of the reasons is Sin. We want to go to Heaven and to lead a good life, but in order to do both, we need to be forgiven for our Sins. And that is exactly where the Gospel comes in 🙂
And it is one reason that Preachers need to Preach both the Love of the Lord and the Law of the Lord.
There is not one of us that can keep all of the Laws of God. If there was, there would be no need for Christ’s Suffering.
But because we can’t lead perfect lives (despite our best efforts), we do need Jesus & the Cross. The Gospel is Good News :). And that is why Preachers need to preach all of it!
