Summary: Whosoever is a formal term for "whoever." That means anyone, you, me, the next-door neighbor, some person living in the desert, on an island far from any major continent. Anyone who is listening to and hearing God's Word.

In verses 1-5:

When we become a Christian, we become part of God’s family, with other believers as our spiritual siblings, brothers, and sisters. God ascertains who the other relatives are, not us. We are basically called to acknowledge and adore them. We know that if we love God and keep His commandments, then we love the children of God. As we love our earthly family, we should love our spiritual (Christian) family. How well do we treat our kindred relatives?

Jesus never guaranteed that complying with him would be simple and easy. In any case, arduous work can be fulfilling if we value the outcomes. One more method of deciphering the last part of verse three could be this, “His orders are not troublesome.” The challenging work and self-restraint of serving Christ is no weight to the individuals who love him. If our load begins to feel too heavy for us to bear, then we can believe that Christ will assist us with bearing it. Jesus overcame the world; therefore, we can overcome the world because Christ lives in us.

• Matthew 11:28-30, Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.

• John 16:33, These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.

In verses 6-10:

“This is he that came by water and blood” may allude to the baptism and crucifixion of Jesus. As of now, there were false teachings that said that Jesus was God just between the time of his baptism and his death. That is, he was conceived as a human until he was baptized, at which time "the Christ" then plunged upon him. However, it later left him before he died on the cross. Assuming Jesus died just as a man, he was unable to have taken upon himself the wrongdoings of the world, and Christianity would be a vacant religion. Just an act of God could remove the punishment that we merit for our sins and transgressions.

“Bear record in Heaven, the Father, the Word, and the Holy Ghost” are one spiritual witness. “Bear witness in earth, the Spirit, and the water, and the blood” are witness to the world. We receive the witness of man through our ears when we listen. When we listen with our heart, we receive the witness of God, for it is greater. If we have Jesus in our hearts, then we have the witness within us.

In the Gospels, God twice plainly announced that Jesus is His Son, at Jesus’ baptism, and at the time of his transfiguration.

• Matthew 3:16-17, And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.

• Matthew 17:5, While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him.

In verses 11-15:

Whosoever has confidence in God’s Son has everlasting life. He is all that we require. We do not have to stand by and wait, because timeless life starts today. We do not have to work for it, since it is now our own. We do not have to stress or worry, since we have been given everlasting life by God himself, and it is ensured.

Certain individuals hope that they will be given everlasting life. John says that we can be certain that we have it. That certainty is founded on God's guarantee that he has given us everlasting life through his Son (John 3:16). This is valid whether we feel that we are near God or far off from him. Everlasting life is not dependent on sentiment feelings. It is based on fact. If we believe in God’s truth, then we have eternal life. God’s truth is his Son, Jesus. Assuming that we may need confirmation to know whether we are a Christian, then we ought to ask ourselves “Have I really dedicated my life to Christ as my Savior and Lord?” If this is so, then we are assured to be one of God’s children.

The accentuation here is on God's will, not our will. When we speak with God, we are not to demand things that we want, rather we talk with him about what he wants for us. Assuming that we adjust our supplications and prayers to his will, he will tune in. We can be sure that when he listens, he will offer us an unmistakable response. That response may not happen immediately, but it will happen. God said it, Jesus did it, I believe it, just do it, it is done.

In verses 16-21:

Theological commentators vary generally in their considerations concerning what sin is, and regardless of whether the demise that it causes is spiritual or physical. Paul composed that a few Christians had died due to them taking communion disgracefully (1 Corinthians 11:27-30), and Ananias and Sapphira were immediately struck dead when they lied to God (Acts 5:1-11). Blaspheming against the Holy Spirit brings about spiritual death, and the book of Hebrews portrays the spiritual death of the individual who betrays Christ.

• Mark 3:29, But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation.

• Hebrews 6:4-6, For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, And have tasted the good word of God, and the powers of the world to come, If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.

John was most likely thinking about the individuals who had left the Christian faith and joined those who were against Christ. By dismissing the only method of salvation, these individuals were putting themselves far from prayer. Regardless of whether we know what the “sin unto death” is, we have no certain method of knowing whether someone in particular has submitted it. In this way we should keep appealing to God for our friends, family, and Christian siblings. We are to leave judgment to God.

Christians submit sins, obviously, however they request that God pardon them and afterward they keep serving him. God has liberated them from their subjection to Satan, and he continually guards them from Satan’s assaults. The remainder of the world does not have the Christian's opportunity to comply with God. Except if they come to Christ in confidence, their only option is to comply with Satan. There is no center ground, individuals either have a place with God and submit to him, or they live under Satan’s influence.

An idol is anything that substitutes for the genuine faith. An idol is whatever denies the full deity and humanity of Christ. An idol is any human thought that professes to be more definitive than the Bible. An idol is any loyalty to anything else that replaces God as the focal point of our lives.

Our opinion on Jesus Christ is integral to our instructing, lecturing, and living. Jesus is simultaneously completely God and completely human. He came to earth to die in our place for our transgressions. Through confidence and faith in him, we can have everlasting life and the ability to do his will. What is our response to the most important question of all time that we might pose, who is Jesus Christ to me?
