'Purpose' in the Bible

but when it is time for the trumpet call of the seventh angel, when he is about to sound, then the mystery of God [that is, His hidden purpose and plan] is finished, as He announced the gospel to His servants the prophets.

These [kings] have one purpose [one mind, one common goal], and they give their power and authority to the beast.

For God has put it in their hearts to carry out His purpose by agreeing together to surrender their kingdom to the beast, until the [prophetic] words of God will be fulfilled.

Then I fell down at his feet to worship him, but he [stopped me and] said to me, “You must not do that; I am a fellow servant with you and your brothers and sisters who have and hold the testimony of Jesus. Worship God [alone]. For the testimony of Jesus is the spirit of prophecy [His life and teaching are the heart of prophecy].”
