'Practise' in the Bible

If we say that we have fellowship with him, and walk in darkness, we lie, and do not practise the truth.

Whoever has been begotten of God does not practise sin, because his seed abides in him, and he cannot sin, because he has been begotten of God.

In this are manifest the children of God and the children of the devil. Whoever does not practise righteousness is not of God, and he who does not love his brother.

and whatsoever we ask we receive from him, because we keep his commandments, and practise the things which are pleasing in his sight.
