It's my life. I'll do what I want.

 Read Judges 14. 

During this time the nation of Israel lived under the oppressive rule of the Philistines.  In response, God chose a man named Samson to liberate His people.  From Samson's early years, "the Spirit of the LORD began to stir him" (13:25).  The angel of the LORD gave his parents instructions on how to raise him.  Samson would be under the commitments of a Nazarite (not Nazarene).  He was not to drink any alcohol, be strict about what he ate, and not to cut his hair.  In the teaching from Moses, this was a voluntary vow for a period time to separate oneself for a special service to God.  The Bible provides instances where such a vow was made by the parents for the life of their child.  Such was the case with Samson, Samuel, and John the Baptist. 

Samson is renowned for his physical strength.  But he was a man who violated his vow repeatedly with moral weaknesses.  Instead of seeking a godly woman for a wife from Israel, he lusted after a Philistine woman who did not worship the LORD.  The Mosaic Law prohibited such a union.  He would not listen to God's word, nor the wisdom and objections of his parents.  Why?  Because "she is right in my eyes" (14:3). 

Samson's physical strength caused him to believe he was invincible.  This type of pride always leads to a downfall.  At the celebration leading up the marriage, his wife-to-be demonstrated her loyalty to her own people, not Samson.  Her heart was full of deceit.  It cost thirty men their lives and the woman was given to another.  Verse 4 is not an endorsement by God of Samson's sin.  Rather, God had a bigger plan to unfold and overthrow the Philistines.  He would use this occasion to begin the process. 

Insights from a bad example:

1. Concerning Parents.

"Children obey your parents in the Lord, for this is right.  Honor your father and mother (this is the first commandment with a promise) that it may go well with you and that you may live long in the land." (Ephesians 6:1-3)  When a child grows to be an adult, they are responsible for their own behavior before the Lord.  While they may not be under the obedience of parents, for all-time they are to honor their parents. 

2. Concerning Temptations.

The first sin was one prompted by the lust of the eyes.  Eve "saw that the tree was good for food, and that it was a delight to the eyes..." (Genesis 3:6).  1 John 2:16 warns us, "For all that is in the world-the desires of the flesh and the desires of the eyes and pride in possessions-is not from the Father but is from the world." 

3. Concerning Sin.

The desire to live life according to one's own wishes is rebellion against God's ownership.  It is this very sin that sent Jesus to die on the cross.  "All we like sheep have gone astray; we have turned every one to his own way; and the LORD has laid on him the iniquity of us all" (Isaiah 53:6) 

4. Concerning God.

The LORD is in control, even when a person sins.  No matter what, He uses every situation in our lives for His glory and His purposes.  "Surely the wrath of man shall praise you" (Psalm 76:10.  "And we know that for those who love God all things work together for good, for those who are called according to his purpose" (Romans 8:28).
