Life is amazing, tiring and frustrating even when you don’t know you’re purpose or have a personal relationship with God. Now throw in the desire to fulfill the purpose God has shared with you during your time together and you become very aware of and intimate with diligence. It is a gift and a character trait developed in the daily pursuit of knowing God more intimately to glorify Him here on earth. It is developed and strengthened along the journey of life.

Hebrews 6:10-12 (Amplified Bible)

10For God is not unrighteous to forget or overlook your labor and the love which you have shown for His name’s sake in ministering to the needs of the saints (His own consecrated people), as you still do.
    11But we do strongly and earnestly] desire for each of you to show the same diligence and sincerity [all the way through] in realizing and enjoying the full assurance and development of [your] hope until the end,
    12In order that you may not grow disinterested and become [spiritual] sluggards, but imitators, behaving as do those who through faith (by their leaning of the entire personality on God in Christ in absolute trust and confidence in His power, wisdom, and goodness) and by practice of patient endurance and waiting are [now] inheriting the promises.
