2 Peter 1:19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: 20 Knowing this first, that no prophecy of the scripture is of any private interpretation. 21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
1 Corinthians 1:9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord. 10 Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
1 John 1:3 That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. 4 And these things write we unto you, that your joy may be full. 5 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. 6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: 7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.
2 Corinthians 12:And lest, when I come again, my God will humble me among you, and that I shall bewail many which have sinned already, and have not repented of the uncleanness and fornication and lasciviousness which they have committed.
Until you define uncleanness as listed among these sexual sins, you cannot prove that it is just my "private interpretation".
Many godfearing believers are glossing over the term uncleanness as referenced in the N.T. They have yet to define it to say that by definition of uncleanness as referred to the N.T., it does not means masturbation, only because they can't, and so they will not do it.
So in other words, they have yet to offer their "private interpretation" of what uncleanness is as listed as a work of the flesh and among the sexual sins in the N.T.
Jesus Christ is in them and is waiting for them to call on Him to deliver them from that sin, but apparently, they need to call on Him to help them define uncleanness in the N.T.
