Who was true worshiper in bible?

Answer 1

In his conversation with the woman at the well, Jesus Christ prophesied of a time when the true worshippers would worship God by the spirit.

John 4:23 "But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him."

On the day of Pentecost, the fulfillment of this prophecy became a reality. This truth was later evident in a letter from Paul to the Corinthian believers. They understood it had become possible for worshippers to pray in the spirit, and that this was by speaking in tongues.

I Corinthians 14:15,18 "What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. I thank my God, I speak with tongues more than ye all:"

When we become born again of God’s spirit, we are filled with the power of the holy spirit. Besides praying with our understanding, we can pray in the spirit, thus worshiping the true God by the spirit, as Jesus Christ had prophesied.
