Jesus said to them, Ye are they who justify yourselves before men but God knows your hearts.

Luke 16:15, Jesus, Jes'ian, Jesian

It will fall on you to give a testimony. Settle it in your hearts not to meditate beforehand about what ye shall answer. I will give you the words and wisdom which your adversaries shall not be able to refute or deny.

And watch yourselves, lest at any time your hearts be overcharged with self-indulgence, and drunkenness, and cares of this life, and that day comes and you are unaware and unprepared. For, as a snare, it shall come on all who dwell on the face of the earth.

Blessed are the pure of heart for they shall see God.
