When a matter is mentioned as the “one thing” it is most important. No one would be casual to mention this. In this case Jesus, King David and Apostel Paul have pointed to this. Do we persue this one thing to our advantage or ignore it to our peril?
The Bible says about one thing. One thing I have desired of the LORD, That will I seek: That I may dwell in the house of the LORD All the days of my life, To behold the beauty of the LORD, And to inquire in His temple. ( Psalm 27:4 NKJV) Here we read that the one thing, the most important matter is to desire to dwell in Lord temple all days of our life. And while we are there, in Gods temple, to be able to contemplate and see the beauty of the Lord as well as enquire and find out matters, search and know Gods will in our live situations.
