'Petition' in the Bible
But the angel said to him, “Do not be afraid, Zacharias, for your petition has been heard, and your wife Elizabeth will bear you a son, and you will give him the name John.
Then they said to Him, “The disciples of John [the Baptist] often practice fasting and offer prayers [of special petition], and so do the disciples of the Pharisees; but Yours eat and drink.”
It is not you who chose me, but it is I who chose you and appointed you that you might go and be fruitful and that your fruit might remain; so that whatever petition you present to the Father in my name He may give you.
With all prayer and petition pray at all times in the Spirit, and with this in view, be on the alert with all perseverance and petition for all the saints,
always offering every prayer of mine with joy [and with specific requests] for all of you,
Don’t worry about anything, but in everything, through prayer and petition with thanksgiving, let your requests be made known to God.
Therefore He is able also to save forever (completely, perfectly, for eternity) those who come to God through Him, since He always lives to intercede and intervene on their behalf [with God].
