'Diligent' in the Bible

"So be very diligent to love the LORD your God,

Be diligent and take precautions so that you do not neglect your responsibility in this matter. Why should the kingdom sustain any more damage?

The diligent will take control, but the lazy will be put to forced labor.

The lazy person craves, yet receives nothing, but the desires of the diligent are satisfied.

Whoever does not discipline his son hates him, but whoever loves him is diligent to correct him.

Pray in the Spirit at all times with every kind of prayer and request. Likewise, be alert with your most diligent efforts and pray for all the saints.

But we want each of you to continue to be diligent to the very end, in order to give full assurance to your hope.
