Half-heartedness has a Price

 Read 2 Chronicles 25. 

King Amaziah's life may be summed up by the statement in verse 2: "And he did what was right in the eyes of the LORD, yet not with a whole heart." 

A half-hearted believer is one who knows better but continues to live in disobedience to God.  Instead of adhering to God's word and remaining faithful, they are swayed by selfish pleasures and the culture around them.  The Apostle James referred to such a person as "double-minded".  "For the one who doubts is like a wave of the sea that is driven and tossed by the wind.  For that person must not suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways." (James 1:6b-8) 

Amaziah did a right thing, followed by a bad decision.  At each key juncture, God, in His faithfulness, sent a prophet with a specific message.  He listened and responded once.  The next time he was so attached to the fantasies he had procured, that he put his faith in them instead of the LORD.  He turned his back on God and suffered the consequences.  Not only did he lose his life, but the people he around him suffered. 

"Blessed are those who keep his testimonies, who seek him with their whole heart." (Psalm 119:2)
