He presented himself alive to them after his suffering by many proofs, appearing to them during forty days and speaking about the kingdom of God. And while staying with them he ordered them not to depart from Jerusalem, but to wait for the promise of the Father, which, he said, “you heard from me; for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.”
The word "baptism' has been a hotly disputed term in church circles for many years. Some dogmatically adhere to an immersion only formula.. others ascribe to a pouring or sprinkling methodology. It seems to me that those who do that miss the heart of the idea - that a new soul has responded to Christ's invitation. Baptism reminds me of the many who came with repentant hearts to John in the Jordan River. And in response John symbolized God's forgiveness with an act of cleansing with water.
The idea of being baptized with the Holy Spirit seems to be a bit different, but somewhat similar, concept. Jesus spoke these words to his disciples and those who had already been baptized with water. In speaking this promise Jesus tells us two things: 1) Christians have an ongoing need for forgiveness and empowering; 2) God is present to respond to those needs. What seems odd however is how some feel that such a baptism is a one-time ecstatic event instead of an ongoing process of cleansing and filling.
I repent Lord. Baptism me afresh in your Spirit. Fill me Lord. I so need you.
