In the Gospels 3 types of baptism are mention.
Baptism with water
Baptism with fire
Baptism with the Holy Spirit
If taken literally no person could survive fire so a meaning other than this is intended.
Both water and fire symbolise cleansing in this case the heart, and the Holy Spirit signifies that this is a spiritual event of the heart, not just a repetitive ritual. The person must truly believe in the Lord in their heart, to become a confirmed believer.
An outward ceremony does not guarantee this according to the verse below.
21 “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’ Matthew 7:21-23
To my understanding, outward baptism has been an administrative function by churches to maintain records of membership but acceptance into the Kingdom of God is conditional upon one doing the will of the ‘Father’.
So true baptism in this day, according to Jesus and entering the Kingdom of God, can only be attained by doing the Will of the Father. And in this day, the Father’s Will is revealed to us.
Say, Lo! The Father is come, and that which ye were promised in the Kingdom is fulfilled! This is the Word which the Son concealed, when to those around Him He said: ‘Ye cannot bear it now.’ And when the appointed time was fulfilled and the Hour had struck, the Word shone forth above the horizon of the Will of God. Beware, O followers of the Son, that ye cast it not behind your backs. Take ye fast hold of it. Better is this for you than all that ye possess. Verily He is nigh unto them that do good. The Hour which We had concealed from the knowledge of the peoples of the earth and of the favoured angels hath come to pass. Say, verily, He hath testified of Me, and I do testify of Him. Indeed, He hath purposed no one other than Me. Unto this beareth witness every fair-minded and understanding soul. (Baha’u’llah)
