New World Translation

John 3:36 The  one who exercises faith in the Son has everlasting life; the one who disobeys the Son will not see life, but the wrath of God remains upon him.

On the evening before his death, Jesus told his disciples: “Exercise faith in God; exercise faith also in me.” (John 14:1) So we need to exercise faith not only in Jehovah but also in Jesus. How can you exercise faith in Jesus? Let us consider three ways. Note that John contrasted exercising faith with being disobedient. Therefore, you exercise faith in Jesus when you obey him. You obey Jesus by following “the law of the Christ,” that is, all that he taught and commanded. (Gal. 6:2) You also obey Jesus by heeding the guidance he provides through “the faithful and discreet slave.” (Matt. 24:45) By obeying Jesus, you will have the strength to endure stormlike adversities.​—Luke 6:47, 48.

“BUILD YOURSELVES UP ON YOUR MOST HOLY FAITH”

Once, a man cried out to Jesus: “I have faith! Help me out where I need faith!” (Mark 9:24) He had a measure of faith, but this man modestly recognized that he needed more faith. Like this man, all of us at some point will need more faith. And all of us can strengthen our faith now. As we have seen, we strengthen our faith when we study God’s Word and meditate on it, which will deepen our appreciation for Jehovah. Our faith will also grow stronger when we​—along with fellow believers—​worship Jehovah, publicly declare our hope, and persevere in prayer. Moreover, when we strengthen our faith, we receive the greatest reward of all. God’s Word urges us: “Beloved ones, build yourselves up on your most holy faith . . . in order to keep yourselves in God’s love.”​—Jude 20, 21.

Faith is simply the conviction that something is true. When you believe in the Lord Jesus Christ as the One who died on the cross to pay for your sins and rose again for His promise of everlasting life, you are guaranteed everlasting life. For you, that means you must first "repent" (i.e. change your mind) from your false JW beliefs and instead place your faith in Jesus Christ as God in the flesh (John 1:1-14 KJV).

JW is a non-Christian cult that denies fundamental Bible doctrines such as the deity of Christ, the Trinity, salvation by grace alone through faith alone in Christ alone, bodily resurrection, and eternal torment in the lake of fire for unbelievers. There is nothing remotely "Christian" about JW. Get away from them before it's eternally too late.

Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him for it. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).

"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).
