Samson's life is one of contradiction. First, he was to be "a Nazirite, set apart to God from birth" (Judges 13:5), yet he continually broke his vow. The Spirit of God came upon him many times, giving him great strength to fight the Philistines, the oppressors of the Israelites. At the same time, however, Samson was a womanizer and a vengeful man, full of sin. Samson's life illustrates that giving in to temptation leads to sin, that God will use even a sinful man to enact His will, and that God will not let us escape the consequences of our sin.
Samson. He didn't gain power from his hair. God had given him the power. he was taken by the Philistines after his hair was cut. Even though it grew he had no power.. he called upon God asking to give him strength one more time. I don't believe God will use a sinful man to do his will. Will he send a pedophile to teach a children's ministry? Or a profane man to minister to a church? There was a covenant on Samson when his mother conceived. The ultimatum was that no razor should touch his head. When Samson's hair was cut the Bible says that he did not know that the spirit of God had left him. To contrast it to present time.. . A lot of times Christians give in to things that God said we must set ourselves a part from.. . The more we do it we become desensitised to the holy spirit and we don't see that what we are doing is wrong.
