The Sin unto Death

This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us. And if we know that He hears us in whatever we ask, we know that we have the requests which we have asked from Him. If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this. All unrighteousness is sin, and there is a sin not leading to death. (1 John 5:14–17)At first glance, verse 16 appears to introduce an abrupt change of subject. But upon further consideration, the connection of verses 16 and 17 to verses 14 and 15 becomes clear. By giving one important exception, John illustrates in a contrasting manner the extent of God’s promise to answer prayer. When a believer sees a brother (a real or professing believer) committing a sin not leading to death, the apostle writes, he shall ask and God will for him give life to those who commit sin not leading to death. On the other hand, there is a sin leading to death, and the apostle did not advise Christians to make request for this sin. . . .
