Born again (that is, saved) persons have direct access to the Father through the Son with the assistance of the Spirit, so no human intercessor is needed. A sincere believer in Christ can pray directly to the Creator and King of the universe! ...you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices to God through Jesus Christ. (1 Peter 2:5, NKJV)
Through His word, the Bible, God prescribed two ordinances for His church, believers' baptism, discussed above, and the Lord's supper, a symbolic, moving picture of Christ's body, which was broken for believers, and His blood, which was shed for believers. The Lord's supper is an ordinance for saved persons who are spiritually prepared (1 Corinthians 11:23-32).
Membership in our church is a privilege offered to those who profess salvation in Jesus Christ by their words and actions, including being baptized, as described above. Then, those who gladly received his word were baptized; and that day about three thousand souls were added to them. And the Lord added to the church daily those who were being saved. (Acts 2:41, 47b, NKJV)
While God has put the civil authorities in place (Romans 13:1-7), the church must not interfere in civil affairs, and the state must not intrude into the affairs of the church. There should not be any sort of alliance between the church and the civil government.
