There were a number of men that gathered themselves unto David at the cave:

I Samuel 22:1 David therefore departed thence, and escaped to the cave Adullam: and when his brethren and all his father’s house heard it, they went down thither to him.

  2 And every one that was in distress, and every one that was in debt, and every one that was discontented, gathered themselves unto him; and he became a captain over them: and there were with him about four hundred men.

It doesn't sound like they were great warriors, since the description of them had been:

"every one that was in distress, and every one that was in debt, and every one that was discontented"

Wouldn't warrior type men typically consider men like this to be losers?

So, after these men fellowshipped with David for a while, did they change?

Did they begin to be more like David?

Is it possible that some of these "losers" became those that David later wrote about?

II Samuel 23:8 These be the names of the mighty men whom David had: The Tachmonite that sat in the seat, chief among the captains; the same was Adino the Eznite: he lift up his spear against eight hundred, whom he slew at one time.

  9 And after him was Eleazar the son of Dodo the Ahohite, one of the three mighty men with David, when they defied the Philistines that were there gathered together to battle, and the men of Israel were gone away:

  10 He arose, and smote the Philistines until his hand was weary, and his hand clave unto the sword: and the LORD wrought a great victory that day; and the people returned after him only to spoil.

  13 And three of the thirty chief went down, and came to David in the harvest time unto the cave of Adullam: and the troop of the Philistines pitched in the valley of Rephaim.

  14 And David was then in an hold, and the garrison of the Philistines was then in Bethlehem.

  15 And David longed, and said, Oh that one would give me drink of the water of the well of Bethlehem, which is by the gate!

  16 And the three mighty men brake through the host of the Philistines, and drew water out of the well of Bethlehem, that was by the gate, and took it, and brought it to David: nevertheless he would not drink thereof, but poured it out unto the LORD.

  20 And Benaiah the son of Jehoiada, the son of a valiant man, of Kabzeel, who had done many acts, he slew two lionlike men of Moab: he went down also and slew a lion in the midst of a pit in time of snow:

If so, then these men had certainly become more like David.

Then wouldn't it be similar for us?

If we spend more time fellowshipping with Jesus, won't we become more like Jesus?
