You did not answer my questions. Regeneration obtains spiritual union before and after Pentecost. Look at the OP and try to refute what I said. Where there is spiritual union there is indwelling as there can be no "union" unless the Spirit of God is UNITED with your spirit - that is Indwelling - as union is impossible apart from indwelling.
I have already dealt with every text in the New Testament that you think refers to future indwelling after Pentecost. No one has been able to overturn the interpretation I have provided.
The baptism in the Spirit is an INSTITUTIONAL immersion and the church is an INSTITUTIONAL qualified public house of worship, with public qualified ministers who administer public qualified ordinances - that is the context of 1 Tim. 3:15.
Are you saying that every believer under the Old Covenant had the indwelling of the Spirit in same way that we now under the new One have Him?
