"Therefore say to the house of Israel, 'This is what the Sovereign LORD says: Repent! Turn from your idols and renounce all your detestable practices!" (Ezekiel 14:6)
Each Easter many Christians renew the vows of their baptism, beginning with, "I renounce Satan and all his works and all his empty promises."
Renunciation is a declaration before the kingdom of darkness that I will no longer make a home for sin or the deceptions and power behind it. I no longer agree with the lies that have been buried in my heart and my thoughts.
Specifically renouncing our enemies brings victory. For example, one might declare, "In the name of Jesus I renounce fear."
"In the name of Jesus, I renounce a spirit of rejection."
"In the name of Jesus I renounce lust...loneliness...a spirit of anger, resentment and bitterness...hatred."
"In the name of Jesus I renounce the lie that everything is my fault"
"In the name of Jesus, I renounce the idol of popularity and recognition"...etc.
After taking one group through some renunciation, some people received significant help because of what God had already revealed to them. Others expressed a general sense of newness. One man said, "I feel as though I have taken a spiritual shower."
When the Lord said to Moses, "I will be an enemy to your enemies." (Exodus 23:22), He did not mean that Moses would just sit and watch. He meant that as Moses fought, so would God.
Moses carried God's authority to fight. In Christ, we too have authority over our enemies who seek to destroy us. We can take our stand against them through repentance, forgiveness and renunciation. Then we declare the truth of their defeat by saying, "In the name of Jesus, I command every spirit that I have renounced to leave me right now."
