While there is an inaugural event, there could be subsequent baptisms of the Holy Spirit for particular reasons as in Acts 4. However, the Spirit of the Lord wants us to know that we must apply 3 principles to help us to continue in the same power and authority that came upon us at the first event. The Lord says that these are the principles of
(1) abiding
(2) growth and
(3) fellowship with the Spirit. There are more but this is ok for now.
The principle of abiding is found in John 15: 1-6.
The picture is one of a vine, a gardener and fruit. The branches spring out of Christ and bear fruit because He is the Living Word. There are other similies that can be used. In order to abide in Christ, therefore, we need to imbibe the Living Word. We spoke prior to this about the imagery of the newborn babe desiring the sincere milk of the word in order to grow thereby (1 Pet 2: 2). Since the Spirit is on Christ and is the power of His word, those who abide in His word which is spirit and life will receive a continual flow of fruit of the Spirit (Gal 5: 22,23) and power which will manifest in healings, signs and wonders, prophecy etc as seen in the book of Acts.
The second is the principle of growth (they are all interelated) after the order of Psalm chapter 1.
To bear the fruit and power of the Spirit, one must remain connected to the “rivers of water” which is the Holy Spirit in Eze 47 which brought life, increase, provision and healing (Eze 47: 19). The water in Jn 7: 38 is also the Holy Spirit who flows out of the belly or innermost being of the one whom He fills. He will pour out of the believer in power and authority, bring life, healing, increase and provision to all those who receive His ministry. He is the river of life in Rev 22: 1 flowing out from the throne and the Lamb.
You cannot maintain the baptism of the Holy Spirit without a life of fellowship with God the Father and the son. This brings us to the principle of the fellowship of the Spirit (Philomen 2: 1) which brings us to the heart of God. This is the life of prayer, worship, intercessions (Rom 8: 28), following the patterns of the Spirit in unity, peace, communion etc as we learned in Acts 2. He is the one who abides in us by the anointing to teach us all things, comfort us and cause us to abide in God (1 Jn 2: 27). He is the promise or gift of the Father which Paul exorted Timothy to “stir up” in him (1 Tim 4: 4). Don’t allow the power of the Spirit to remain dormant and unused in your life. Use every opportunity to use it like the disciples did in the book of Acts. Blessings and God bless. Homework is to look for the phrases in Acts indicating that the disciples continued in the power.
