Summary: Bible Study
I. ETERNAL SECURITY IS VERY IMPORTANT - Vs 11-13
First because it says that Jesus Paid it all !
We cannot have Peace unless we are Secure
We cannot really know the Lord unless we Trust Him
We cannot Help others, while we are Helping ourselves
We cannot Win people, if we don’t trust His keeping power
We cannot Succeed in Life, unless we are Secure in Jesus
We cannot stand the Storms of Life without His keeping power
II TO DOUBT OR DENY ETERNAL SECURITY WILL NEGATE YOUR EFFECTIVENESS IN PRAYER (vs. 14-15).
1 John 5:14-15 (quickview)  And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
You will notice the conjunction "and" at the beginning of v. 14. This means that our "confidence" in prayer is directly related to our assurance of salvation. Our text says that God wants us to seek His will, then to come before Him with confidence and make our petitions and our desires known (v. 15), and then to "know" that He has heard and will answer our prayers. Matthew 7:7-11 (quickview)  makes it plain that God delights in answering our prayers and supplying our needs as much as a good earthly father enjoys doing things for his children.
III THE "SIN UNTO DEATH" REFERS TO BELIEVERS ONLY (VERSE 16)
Many people mistakenly equate this sin and this passage with the "unpardonable sin". However, that is a serious scriptural error. The "unpardonable sin" is committed by an unbeliever (Matthew 12:31-32 (quickview) ) and the "unpardonable sin" leads to spiritual death and separation from God in hell(the second death).
1. Verse 16 clearly declares that there is "sin which leads unto death". There is a lifestyle, which if continued by the believer, will result in premature physical death.
2. So serious is this lifestyle, that there is no need for a fellow Christian to even pray for that person. Hebrews 12:5-11 (quickview)  clearly declares several things about God’s chastening of believers:
(4) Now this means that a believer is not going to suddenly make a small mistake and
be killed by God.
3. It is imperative that the believer continually remember Biblical examples of "the sin unto death". (1) Acts 5:1-11 (quickview) (2) I Corinthians 5:1-5 (quickview) (3) I Corinthians 10:1-13 (quickview) (4) I Corinthians 11:26-32 (quickview) (5) Hebrews 10:26-31 (quickview) .
IV THERE IS NO NEED FOR A FELLOW CHRISTIAN TO PRAY FOR A BELIEVER WHO HAS COMMITTED THIS SIN (VERSE 16)
1. We are assured that God hears and answers prayer (verses 14-15).
2. We are commanded to pray for brethren who fall into sin (verse 16).
3. We are told, however, there is no need to pray for one who has committed "the sin unto death" (verse 16).
