“Now the great thing is this: we are consecrated and dedicated to God in order that we may thereafter think, speak, meditate, and do, nothing except to His glory. For a sacred thing may not be applied to profane uses without marked injury to Him.
If we, then, are not our own but the Lord’s, it is clear what error we must flee, and whither we must direct all the acts of our life. We are not our own: let not our reason nor our will, therefore, sway our plans and deeds.
We are not our own: let us therefore not set it as our goal to seek what is expedient for us according to the flesh. We are not our own: in so far as we can, let us forget ourselves and all that is ours.
Conversely, we are God’s: let us therefore live for Him and die for Him. We are God’s: let His wisdom and will therefore rule all our actions. We are God’s: let all the parts of our life accordingly strive toward Him as our only lawful goal.”
