1 Chronicles 12:38 All these men of war, that could keep rank, came with a perfect heart to Hebron, to make David king over all Israel: and all the rest also of Israel were of one heart to make David king.
Let's look at the character of the men who joined themselves to David. First of all, they were men of war who could keep rank with a perfect heart. They were men who worked in cooperation with one another – each knowing his position and so able to give orders as well as obey them. They walked in fellowship one with another. Secondly, they were single-hearted men, wholeheartedly devoted to making David king over Israel, and their minds were set to advance David’s kingdom.
If we’re going to advance Yeshua’s (Jesus’) Kingdom, we'll work like David's mighty men with single hearted cooperation and a perfect heart toward our Lord. He said “all men” will know that we are His disciples if we have “love for one another.” [John 13:35] How simple is that?
