The problem that seems to be most probable, is interpreting scripture accurately. The scripture tells us that the fear of the Lord is the beginning of wisdom and knowledge. I for one, like to depend on the Holy Spirit to give me understanding, on what is the true interpretation, concerning the scripture that is before me. I always read within context of what is stated before and after a certain scripture.
I also am more conservative in my approach to the understanding of scripture because of a fear of God concerning a right interpretation. I don’t want to be in error and do not want to lead someone wrong. I believe from scripture that God is holy and will have no mixture of light and darkness.
2 Corinthians 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,
18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
2 Corinthians 7:1 Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
2 Timothy 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
2 Timothy 3:17 That the man of God may be perfect, throughly furnished unto all good works.
Philippians 2:12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
Philippians 2:13 For it is God which worketh in you both to will and to do of his good pleasure.
I think we all need to be more like Paul, in not shunning, teaching the whole counsel of God. We don’t need to debate one another in our beliefs but consider one another to provoke unto love, exhorting one another, and sharpening one another concerning our walk with God.
