It is also true that the Great Commission refers only to Matthew 28:19-20. But my comments to you were related to everything entailed in the Great Commission and not the Great Commission alone. In context, here is the Great Commission starting at verse 16 (emphasis mine):
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, [even] unto the end of the world. Amen.
And there went great multitudes with him: and he turned, and said unto them, If any [man] come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
And whosoever doth not bear his cross, and come after me, cannot be my disciple.
For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have [sufficient] to finish [it]? Lest haply, after he hath laid the foundation, and is not able to finish [it], all that behold [it] begin to mock him, Saying, This man began to build, and was not able to finish.
Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand? Or else, while the other is yet a great way off, he sendeth an ambassage, and desireth conditions of peace.
So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
Salt [is] good: but if the salt have lost his savour, wherewith shall it be seasoned? It is neither fit for the land, nor yet for the dunghill; [but] men cast it out. He that hath ears to hear, let him hear. Luke 14:25-35
Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God . The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit .
And no man hath ascended up to heaven, but he that came down from heaven, [even] the Son of man which is in heaven. And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: That whosoever believeth in him should not perish, but have eternal life. For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. excerpted from John 3
Jesus answered them, I told you, and ye believed not: the works that I do in my Father's name, they bear witness of me. But ye believe not, because ye are not of my sheep, as I said unto you. My sheep hear my voice, and I know them, 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. I and [my] Father are one. John 10:25-30
Do not fret too much over these threads, AG. Some of the conversations are much ado about very little in the long run. Sometimes points that we try so hard to make in debate we find ourselves on the opposite side of one year later.....sometimes, embarrassingly and unwittingly.
