The first one pertains to who Jesus was addressing during His first advent. Mt.15:24 and 10:5-6 make it abundantly clear, He was addressing Israel EXCLUSIVELY.
2Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
But rather in respect to an inward Jew, the Israel of God after the spiritual seed (one) of Christ. Not the Israel of men, after the fleshly seeds (many).
For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:But he is a Jew, which is "one inwardly"; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God. Romans 2:28
If any man of any nation have not the Spirit of Christ the Holy Spirit of God then neither do they belong to Him.
Romans 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
The old testament saints that make up the chaste virgin bride of Christ the church worshiped God by faith and not by sight just as us today. They searched the scriptures looking ahead, we look back to the same demonstration.
1Peter 1:11 Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow.
The Church DID NOT exist then, because the Holy Spirit had not yet arrived, as recorded in Jn.7:39, until at Pentecost, ten days after Jesus ascended into heaven, recorded in Acts 1:9 and in 2:1-3. As such, none of it pertains to the Church The only verses alluding to activities of the Church pertain to BELIEVING Israelites, such as Mt.24:31; Lk.21:36 and in Jn.14:2-3, 28.
And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;And put no difference between us and them, purifying their hearts by faith. Act 15:8
Who and what are the 144,000 Israelites?
