'Reason' in the Bible

For this reason I, Paul, am the prisoner of the Messiah Jesus for the sake of you gentiles.

This is the reason I bow my knees before the Father of our Lord Jesus, the Messiah,

For this reason, take up the whole armor of God so that you may be able to take a stand whenever evil comes. And when you have done everything you could, you will be able to stand firm.

I am sending him to you for this very reason, so that you may know how we are doing and that he may encourage your hearts.
