'Practice' in the Bible

And He has given Him authority to execute judgment, because He is a Son of Man [sinless humanity, qualifying Him to sit in judgment over mankind].

You are of your father the devil, and it is your will to practice the desires [which are characteristic] of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. When he lies, he speaks what is natural to him, for he is a liar and the father of lies and half-truths.

If you know these things, you are blessed [happy and favored by God] if you put them into practice [and faithfully do them].
