Almost saved- One thing the religious-but-lost person lacks; a commitment to follow Jesus

What does it really mean to "believe" on Jesus? Is believing on Jesus really just a mental ascent, or simply agreeing that Jesus is the Truth; or is there more to believing in Jesus than that.

The key to this is that believing in not agreeing with Jesus, but TRUSTING IN Jesus.

Mark 10:17–27 (KJV 1900)

17 And when he was gone forth into the way, there came one running, and kneeled to him, and asked him, Good Master, what shall I do that I may inherit eternal life? 18 And Jesus said unto him, Why callest thou me good? there is none good but one, that is, God. 19 Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Defraud not, Honour thy father and mother. 20 And he answered and said unto him, Master, all these have I observed from my youth. 21 Then Jesus beholding him loved him, and said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me. 22 And he was sad at that saying, and went away grieved: for he had great possessions.

23 And Jesus looked round about, and saith unto his disciples, How hardly shall they that have riches enter into the kingdom of God! 24 And the disciples were astonished at his words. But Jesus answereth again, and saith unto them, Children, how hard is it for them that trust in riches to enter into the kingdom of God! 25 It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God. 26 And they were astonished out of measure, saying among themselves, Who then can be saved? 27 And Jesus looking upon them saith, With men it is impossible, but not with God: for with God all things are possible.

Mark 12:28–34 (KJV 1900)

28 And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all? 29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: 30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. 31 And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these. 32 And the scribe said unto him, Well, Master, thou hast said the truth: for there is one God; and there is none other but he: 33 And to love him with all the heart, and with all the understanding, and with all the soul, and with all the strength, and to love his neighbour as himself, is more than all whole burnt offerings and sacrifices. 34 And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. And no man after that durst ask him any question.

Luke 18:18–27 (KJV 1900)

18 And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life? 19 And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God. 20 Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother. 21 And he said, All these have I kept from my youth up. 22 Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me. 23 And when he heard this, he was very sorrowful: for he was very rich. 24 And when Jesus saw that he was very sorrowful, he said, How hardly shall they that have riches enter into the kingdom of God! 25 For it is easier for a camel to go through a needle’s eye, than for a rich man to enter into the kingdom of God. 26 And they that heard it said, Who then can be saved? 27 And he said, The things which are impossible with men are possible with God.
