This is the reason as to why I have a problem with the so-called "sinners prayer". There are MANY who believe that they're save and on their way to heaven because several years ago they recited a sinners prayer by repeating a rote prayer from their pastor. Little do they know...they could be on their way to an eternity in the Lake of Fire.
Matthew 7:16,20 - Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Wherefore by their fruits ye shall know them.
If someone contintues to live a lifestyle of sin without genuine repentance, then I would question whether or not this person has truly been regenerated of the Holy Spirit. Faith AND repentance are two sides of the SAME coin.
Luke 13:3 - I tell you, Nay: but, except ye repent, ye shall all likewise perish
Matthew 7:21-23 - Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Anyone can call Jesus Lord with their mouths, bu the Lord knows their hearts.
Romans 10:10 - For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
James 1:22 - But be ye doers of the word, and not hearers only, deceiving your own selves.
James 2:14,19 - What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him? Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
Even the devils believe, they however don't possess saving faith. They're NOT going to turn from their wickedness but follow their master the prince of this world until their alotted time in the Lake of Fire.
2 Corinthians 13:5 - Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
Jude 1:4 - For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
TRUE salvation doesn't lead to antimonianism, it leads to a changed life of repentance from sin because they are a NEW creation in Christ.
Galatians 5:19-21 - Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
The above passage speaks of those who live in such manner WITHOUT repentance will not inherit the kingdom of God. A genuine believer WILL and CAN sin, however, if there is no struggle between the flesh and the spirit...then I would question whether this person has truly been born of God.
Romans 7:18-23 - For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. For the good that I would I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. I find then a law, that, when I would do good, evil is present with me. For I delight in the law of God after the inward man: But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Too many professing Christian take John 10:27-29 out of context and believe that we can go to heaven regardless of our sinful lifestyle. On the contrary, Jesus stated otherwise:
John 10:27-29 - My sheep hear my voice, and I know them (have an intimate relationship), and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
Luke 6:46 - And why call ye me, Lord, Lord, and do not the things which I say?
