The battle became fierce against Saul. The archers hit him, and he was severely wounded by the archers. Then Saul said to his armorbearer, "Draw your sword, and thrust me through with it, lest these uncircumcised men come and thrust me through and abuse me." But his armorbearer would not, for he was greatly afraid. Therefore Saul took a sword and fell on it.

—1 Samuel 31:3-4

Saul’s death was a sad end to a sad life—the life of a man whose potential and opportunity was squandered.  Saul was providentially given great opportunity, at least outwardly.  He was tall and handsome, looking very “kingly” (1 Samuel 9:2).

Circumstantially, Saul was chosen by God to be the king, though the people’s desire for a king was not right (8:6-9).  But Saul foolishly wasted his God-given opportunities.  How?  Disobedience to God.  In a variety of ways.  Numerous times.

As a result of his repeated disobedience, God took the kingdom from Saul, giving it to David.  And even though David was a loyal servant to Saul (including sparing Saul’s life, not once, but twice!) Saul was driven by the singular quest to kill David.

No one is saying that disobedience to God causes a person to commit suicide.  If that were so, everyone would take his or her own lives.  What this is about is how by continuing in sin (and never really even confessing, much less repenting of our sin) we can unravel our lives and ensure a fate worse than suicide.  What could possibly be worse than suicide?  To face a holy and just God on judgment day and be banished to a place of His eternal wrath is the infinite sad end to any life.

The good news is that Jesus lived and died to save sinners from their sin—both the penalty and the power of sin.  To receive the benefit of what Christ won for His people, trust in Him alone as the only way to be forgiven.  Turn from sin and follow Him.  This is the only way to avoid a wasted life in the here and now, and on into eternity.
