Doctrine of Baptisms 
Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God, Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment. And this will we do, if God permit. 
(Hebrews 6:1-3)
The idea of this whole subject started way back when, but being hesitant to start on such a large and controversial subject, which has been so well documented by eminent Christians, that I delayed and delayed until prompted by the Holy Spirit, and am confident therefore that someone out there will find this series helpful and unbiased. 
It was while my wife was reading from Pat Boone's book "A New Song" and quoted therefrom that I received that warm feeling of acceptance in my inmost being and realised that what was written was truth. 
Pat Boone wrote that when he inadvertently overheard his wife praying in what she called her "prayer language" she was saying "Ave Deum" in a language that she had never learned, but was Latin for "Praise God". 
Hours later, while musing on God's word, the phrase came to mind "give me something to eat" 'and they gave Him fish and honeycomb.' 
The next morning, in the quietness of a room with a closed door, I started to read from the Psalms, and to get the ribbon marker out of the way the Bible was randomly opened and the following red-lettered words from a resurrected and empowered Christ Jesus jumped out to be noticed: 
And while they yet believed not for joy, and wondered, he said unto them, Have ye here any meat? 
(Luke 24:41)
and then
And they gave him a piece of a broiled fish, and of an honeycomb. 
(Luke 24:42)
Those of us who are guided by the Holy Spirit know that these supernatural events continually happen and come to realise that this is confirmation of a spiritual message. 
In this case "Write about what I showed you." 
Further, if we contemplate this Spiritual confirmation, we note that these words were stated by the risen Christ Jesus. 
Because Satan realises that his defeat at the hands of God happened as the result of the resurrection of Jesus of Nazareth, this confirmation could hardly have come from him as a deception of the truth. 
This is confirmed:
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. 
(1 John 4:1-3)
Therefore, from God's word and from the manifesting of God's Spirit, we can be assured that the original prompting came from God Himself. 
In this assurance and using our spiritual discernment let us reach for this hidden treasure that God calls the foundation principles of His doctrine - the beginning stage of the knowledge granted to us and that we so wish to learn.
