1 Peter 1:17

If you address as Father, the One who impartially judges according to each one’s work, conduct yourselves in (reverent) fear (of Him) and with profound respect for Him throughout the time of your stay on earth.  

When we draw near to God in fellowship and prayer, we must respect God. God has never been casual toward His dedication or love for us, especially when He sacrificed Jesus for our redemption. We must also act accordingly toward God and reciprocate the love and respect toward our God and redeemer.
