Perhaps the incident recorded in 2 Samuel 23:15-17 might be of a peculiar nature to an unbelieving soul. Why the waste? Why would David not drink it?
But, what a great service we see, it is not fighting eight hundred Philistines, nor guarding the ground or fighting for the nation when all else left, which in itself was a great service but nothing of that sort is mentioned in this verse. It was simply catering to the will of David, it says ”And David longed, and said, Oh that one would give me to drink of the water of the well of Bethlehem…” No word of order, just a simple wish, not doing which would have not affected their loyalty in any ways whatsoever. But no, they knew who David was, for they deemed their lives less precious.
Alas after such a great sacrifice, the last scene one would expect to see is David not drinking it. What a waste of energy, it might occur to a natural mind. Yeah, as the scripture says, But the natural man does not receive the things of the Spirit of God, for they are folly to him; and he cannot know them because they are spiritually discerned; 1 Corinthians 2:14. Why would David not drink it? Oh, it was because David saw a great sacrifice (that of one’s life) in their action the worthy of which Lord alone could be. Hence he pours it before the lord. What a beautiful picture of devotion. Could he be more worthy then the Jehovah? Certainly not.
Perhaps we can see similar devotion in the action of Mary in the gospel of John 12. A wonderful picture of a true worshiper. For she gave to the Lord all she could, the most expensive gift she had and the glory of her head -her hair. And what was the result of her devotion? It says “…and the house was filled with the odour of the ointment.” Mary knew who lord was, she knew his person, his deity for she was always at the feet of the Lord in listening to his word (Luke 10:39), in distress (John 11:32) and while in worship (John 12:3)
Perhaps a glance at the Calvary might give us a reminder of what Lord is to us and prepare our hearts to do his will.
