The sacraments become effectual means of salvation, not from any virtue in them, or in him that doth administer them; but only by the blessing of Christ,1 and the working of his Spirit in them that by faith receive them.2
21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
Matthew 3:11
11 I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire:
1 Corinthians 3:6-7
6 I have planted, Apollos watered; but God gave the increase.
7 So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase.

1 Corinthians 12:13
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.
