“What you are is God’s gift to you, what you become is your gift to God.”
—Hans urs von Balthasar.
You are right, the Bible does have something to say about the way in which the believer is to conduct himself.
“If you love Me, you will keep My commandments.
Of David. Blessed be the Lord, my rock, who trains my hands for war, and my fingers for battle;
For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ,
You are now a citizen of heaven; act like one.
Give it some thought.
