Matthew 10:32-33 32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
We can go through life and not choose certain things, but there is one thing that can put our soul in jeopardy of entering heaven and that is to deny the Lord who died for us (2 Timothy 2:10-13). 10 Therefore I endure all things for the elect’s sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory.11 It is a faithful saying: For if we be dead with him, we shall also live with him:12 If we suffer, we shall also reign with him: if we deny him, he also will deny us:13 If we believe not, yet he abideth faithful: he cannot deny himself.
Jude the brother of James and servant of Jesus Christ wrote expressly that the called and servants of Christ should contend for the faith, for there are some who of old will creep in secretly turning from the grace of God so that others may hop on board and deny the Lord as well along with them(Jude 1:1-7). 1 Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:2 Mercy unto you, and peace, and love, be multiplied.3 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.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.5 I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.6 And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
Actions do speak louder than words and there will always be some who think if they say they are Christians it is a free ticket to heaven ,yet their works show otherwise and deny the Lord who paid the price to save them!(Titus 1:15-16). 15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.16 They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
