The following quote from Piper's How to Receive the Gift of the Holy Spirit deserves to be pondered by all of us believers in Christ:When you read the New Testament honestly, you can’t help but get the impression of a big difference from a lot of contemporary Christian experience. For them the Holy Spirit was a fact of experience. For many Christians today it is a fact of doctrine.
Does this resonate with you as it does for me? If so, what would it mean for your experience of God and of Christ? Can you think of biblical texts that would indicate a direction that could be taken to move from a doctrinal stance to a practical and experiential one? One such biblical passage would be Luke 11:5-13, where it is said that the Father will give the Holy Spirit to those who ask Him (v. 13).

Here is another important quote from Piper's How to Receive the Gift of the Holy Spirit that should be acknowledge :Jesus says in Acts 1:5 and 8 that baptism in the Spirit means, “You shall receive power . . . and you shall be my witnesses.” This is an experience of boldness and confidence and victory over sin. A Christian without power is a Christian who needs a baptism in the Holy Spirit. I am aware that in 1 Corinthians 12:13 Paul says that baptism in the Spirit is an act of God by which we become a part of the body of Christ at conversion, so that in his terminology all genuine converts have been baptized in the Spirit.

But we have done wrong in limiting Paul’s understanding of the baptism in the Holy Spirit to this initial, subconscious divine act in conversion and then forcing all of Luke’s theology in Acts into that little mold. There is no reason to think that even for Paul the baptism in the Holy Spirit was limited to the initial moment of conversion. And for sure in the book of Acts the baptism in the Holy Spirit is more than a subconscious divine act of regeneration — it is a conscious experience of power (Acts 1:8).
It might be important at this stage of reading through these threads to listen for yourself to Piper's sermon and to study his accompanying notes following through the biblical references he brings forth to support his view.

How would you respond to the following statement from Piper, in How to Receive the Gift of the Holy Spirit? I sometimes fear that we have so redefined conversion in terms of human decisions and have so removed any necessity of the experience of God’s Spirit, that many people think they are saved when in fact they only have Christian ideas in their head not spiritual power in their heart.
