“If a man will do His will, he shall know of the doctrine, whether it be of God or whether I speak of myself” (John 7:17). They that will to do His will shall know. You can see or learn the way as you go along. Remember this, if you know of just one commandment that you have not yet obeyed, you do not deserve to understand another until you are willing to obey the one you do understand. If a man does not love the truth, God will send him strong delusions that he may believe a lie and be damned (2 Thess. 2:8-12). If you know truth and are unwilling to act upon it, you do not deserve to know any further truth. If you keep on despising what truth you do have, then God will take even that away from you. He will send you a strong delusion that you may be deceived, may be deluded and may be damned forever. It is a dangerous thing for one to trample under his foot the word of Almighty God. If you know of even one commandment which you have not obeyed, obey it now. 8. “_I live a good, clean life, I treat everybody right. I pay all my debts, I tell the truth, I am loyal and faithful to my family, and I am just as good as a lot of those folk in the church. The church can’t save you anyhow, so I think I am all right._” Now, you know the answer to that, don’t you? It’s found in the tenth chapter of Acts. I always like to suggest that the man who makes that sort of a statement compare himself with Cornelius. He was a just man. He treated everybody right. He feared the Lord. He prayed to God always. He was charitable. He gave much alms to the poor. And he was such a good man he had won the favor of the Jews over whom he was serving as the head of an army of occupation! He had a good reputation, even among them. Yet he was not good enough to go to heaven without obeying the gospel. He was told to send for Peter, who would speak unto him words whereby he should be saved. He was not yet saved. If you have ever committed just one sin, you cannot go to heaven until that sin is washed away by the blood of Jesus, for sin cannot enter there. Surely there is no one who would say that he had never committed one sin. You don’t have to commit a great big catalogue of sins in order to be lost. Just one unforgiven sin will take you into torment. If you’ve ever done wrong on a single point, then you’ll have to repent of that and obey the gospel in order to go to heaven when you die.
