John 3:5,6 "Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit."
John 4:23,24 "But the hour cometh, and now is, when the true worshipers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. God is a spirit: and they that worship him must worship him in spirit and truth."
Romans 8:16-17 "The Sprit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Romans 10:4 "For Christ is the end of the law for righteousness to every one that believeth."
1 Corinthians 12:1 "Now concerning spiritual gifts, brethern, I would not have your ignorant..........(for the sake of brevity)......
vs.11; But all these worketh that one and the selfsamne Spirit, dividing to every man severally as he will......vs. 13; For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit." vs.27-31; Now ye are the body of Christ, and members in particular. And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healing, helps, governents, diversities of tongues. Are all apostles? are all prophets? are all teachers? are all workers of miracles? Have all the gifts of healing? do all speak with tongues? do all interpret? But covet earnestly the best gifts: and yet shew I unto you a more excelent way."
1 Corinthians 15:39-40 "All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds. There are also celestial bodies, and bodies terrestrial; but the glory of the celestial is one, and the glory of the terrestrial is another............vs. 44; It is sown a natural body; it is raised a spiritual body, There is a natural body, and there is a spiritual body,"
Galatians 3:26-29 "For ye are all the children of God by faith in Christ Jesus: For as many of you as have been baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
Ephesians 4:1-6 "I therefore the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called. With all lowliness and meekness, with longsuffering, forbearing one another in love; Endeavouring to keep the unity of the Spirit in the bond and peace. There is one body, and one Spirit, even as ye are called in one hope of your calling;"
Colossians 3:10-11 "And have put on the new man, which is renewed in knowledge after the image of him that created him; Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free; but Christ is all, and in all."
Titus 3:4-9 "But after that the kindness and love of God our Saviour towards man appeared, Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration and renewing of the Holy Ghost; Which he shed on us abundantly through Jesus Christ our Saviour; That being justified by his grace, we should be made heirs according to the hope of eternal life. This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men. But avoid foolish questions, and genealogies, and contentions, and strivings abot the law; for they are unprofitable and vain."
As I study these Scriptures, one central theme appears to me, and this is just my opinion.......
That when we worship God, regardless of the venue, we must worship Him in spirit. If we worship God in the flesh, then we are not worshiping God but, rather, the traditions of man. We must set aside the "earthly" man when we enter into worship of God. When we fellowship in worship of God with other believers, we must see them "in spirit" and not in their earthly beings. They are our brothers in Christ and are ALL heirs and worthy of being called the children of God.
This is just what I see as I study these Scriptures and I do not demand or expect any one to believe as I do. I'm just offering what I see through the study of these Scriptures.
