'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].

However, because Moses gave you the practice of circumcision (not that it came from Moses, but from the forefathers), you circumcise a male child on the Sabbath.

I am telling you the things I have seen while with the Father; as for you, practice the things you have heard from the Father!"

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 understand these things, how blessed you are if you put them into practice!
