One thing I have asked from the LORD, that I shall seek: That I may dwell in the house of the LORD all the days of my life, to behold the beauty of the LORD. (Psalm 27:4)
One thing. This is a very unifying approach to life, to faith—to whatever. The Hebrew text could actually say: One one I have asked. It may sound redundant, but think about it. Life is filled with one things that we must do, that need our attention. But what is the one One? Or should I say, Who is the only One. Four areas of your life will be changed forever by making the Lord, The One: Priority, Perspective, Purpose, and Practice.
To love the LORD with all your Heart, Soul, Mind and Strength radically changes your words and your works.
In the morning, O LORD, You will hear my voice; in the morning I will order my prayer to You and eagerly watch. (Psalm 5:3)
I will give thanks to the LORD with all my heart; I will tell of all Your wonders. I will be glad and exult in You; I will sing praise to Your name, O Most High. (Psalm 9:1-2)
Whatever your hand finds to do, do it with all your might; for there is no activity or planning or knowledge or wisdom in Sheol where you are going. (Ecclesiastes 9:10)
Glory in His holy name; let the heart of those who seek the LORD be glad. Seek the LORD and His strength; seek His face continually. (1 Chronicles 16:10-11)
Whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks through Him to God the Father. (Colossians 3:17)
Since you have in obedience to the truth purified your souls for a sincere love of the brethren, fervently love one another from the heart. (1 Peter 1:22)
Little children, let us not love with word or with tongue, but in deed and truth. (1 John 3:18)
Your practice must be all-inclusive, all-encompassing, and completely and utterly permeated by and transformed by the Truth. How you pray, how you worship, how you serve, how you work, how you live, and how you love, must be done with a whole heart, and with all your mind, soul and strength. Your practice must reflect Him, and glorify Him. There must be no doubt to Whom you belong; for your actions should be crying out: All that I am belongs to Christ! All that I do, I do because of Christ! For our hearts, our minds, and our works, He is the One one-thing.
