re #2629:
all BELIEVERS.
In scripture, believing can be understood in two different ways. 1) It can refer to a nominal, lukewarm, or shallow faith (Revelation 3:16) that is either mental assent to doctrine (John 5:39-40) or an emotional experience (Luke 8:13) but is not a living and saving, heart faith; or, 2) it can refer to a living and saving, heart faith that is unto righteousness (Romans 10:10) and also tenacious unto the enduring to the end (Hebrews 3:6, Hebrews 3:14, Matthew 10:22).
In order to determine what kind of faith it is talking about any time we see the words "believe" or "faith" we must consider what word, if inserted there, will be more conducive to the doctrine/truth that is according to godliness (1 Timothy 6:3, Titus 1:1). For the Bible's teaching is in accordance with the doctrine that is according to godliness; it does not teach anything that would lead its readers to think that they can live ungodly lives without any kind of repercussions.
Those who have been baptized into one Spirit and have been made to drink into one Spirit, therefore, are those who believe according to definition #2.
@1stcenturylady is right in saying that we must repent of all sin to have the baptism of the Holy Ghost. And Acts 2:38-39 does indeed speak of a conditional promise; the promise being the Holy Ghost,
the condition being repentance and baptism in the name of Jesus Christ for the remission of sins. It is the conditional promise of the Holy Ghost given to
as many as the Lord our God shall call.
So then, repentance is very important. See Matthew 3:8-12, Acts of the Apostles 2:38-39, Acts of the Apostles 3:19, Acts of the Apostles 17:30, Acts of the Apostles 20:21, Acts of the Apostles 26:20, 2 Corinthians 7:10.
