It is clear that baptism is a gate through which all must pass. Immediately after the ordinance, the Holy Ghost must become the companion of those who are redeemed.
Christ set the example. We are obligated to follow the example.
Receiving baptism without also receiving the Spirit renders the event incomplete. Nephi will explain the essential nature of the Holy Ghost in the redemption process in a few more verses. It is clear that the Holy Ghost is the instrumentality by which redemption itself comes. The Spirit is the guide which will lead back to the Lord’s presence. Without the guide, the doctrine of Christ is incomplete.
The water is something that we must pass through to keep the law. It is the companionship of the Spirit which makes you justified, by leading you to do what is right. It is the resulting application of Christ’s blood on your behalf that will sanctify you. (Moses 6: 60.) You cannot receive sanctification without first receiving baptism and then also the Holy Ghost.
Christ’s example is the only one for us to follow to obtain hope for our own salvation. He is the “prototype of the saved man” (Lecture 7, Lectures on Faith, paragraph 9). If it was necessary for Him, it is the more necessary for us.
Baptism is one thing, accepting the Holy Ghost is another. The one is objective, and openly visible when the act happens. The other is internal, involving welcoming a member of the Godhead into your life.
I remember kneeling on an Atlantic beach in the cool sand at the setting of the sun on the day of my baptism. The Atlantic is cold in September, and I was chilled from the ordinance, still wet while kneeling, and shivering as the elders began the ordinance. When, however, they said: “receive the Holy Ghost” I remember becoming warm, beginning at my scalp and flowing downward until my entire body was warm and calm. It was palpable. It was physical. To me the experience was no less dramatic than the descent of the Holy Ghost “in the form of a dove” on the day of Christ’s baptism. It was every bit as objective, as physical and as memorable as any other distinct event in my life.
More importantly, I began to experience the fruits of that event immediately. What followed for me, within the hour of my baptism, was akin to what Joseph and Oliver experienced. (JS-H 1: 73.) Within days I found also that the scriptures began to have far more distinct and clear meaning than ever before, again just as Joseph and Oliver found. (JS-H 1: 74.)
It was clear to me that the Holy Ghost imparts something altogether more significant than what I alone could do, understand, or accomplish. It expanded capacity, enlightened and informed the mind, and led to understanding things which were unknown and unknowable before.
This process is not just mandatory. It is a far superior way to experience life than to live alone, without God in the world. (Alma 41: 11.) It is a blessing, a gift. The “gift of the Holy Ghost” is, without question, the great “gift” coming from God to aid us in our return to Him.
