What happened to, "God prepares a table before me in the presence of my enemies"? It doesn't say, "in the absence of my enemies". It says, "in the presence of my enemies". A reason for this is so they can see the goodness of God in your life and the error of their ways - which can lead them to repentance...
Praying for the death of your fellow human beings is rooted in fear, hatred, revenge and unforgiveness. Wake up your heart to LOVE and FORGIVENESS. God is the Great Judge. He gives life. And He determines when a life should be terminated. Not you! Stay in your lane!
Why pray for the death of others?
People have to make use of the appropriate words - most especially in an enlightened age. Highly spiritually matured and knowledgeable people choose their words carefully. It is far better to use words that make it clear that you desire the evil machinations of your enemies to be destroyed instead of speaking as though you yearn for the individual human being to physically die. ....and going about the place decreeing physical death on people, left, right and center... Such fake decrees cannot be honored by an Almighty, all powerful, all knowing and at the same time, all loving God.
A brother, Emeka Odoemene puts it quite nicely, "God is a loving Father and He is Father to both the righteous and the sinner. We, earthly parents would not kill one (or some) of our children because he oppresses other children. So, people should stop expecting God to answer their prayers to kill other humans for some wicked acts. He owns all lives and would take them when he wants."
"Suffer not a witch to live."
That instruction was based on the level of enlightenment of the people of that day - Moses' day and era. The Paradise Father does not see that as "His Word". Another example is: "An eye for an eye; a tooth for a tooth." And you know Jesus made it clear that it is not the Word of God or that our Heavenly Father doesn't want us to implement that. But Moses and his crew taught that. Knowledge has increased. A greater enlightenment has come. We should know better. We are guided by the perfect law of liberty and love. Vengeance belongs to God. Let Him do His thing.
2 Timothy 4:4
"Alexander the coppersmith did me great harm; the Lord will pay him back for his deeds." - Paul
This clearly falls in line with God's modus operandi. Paul knew better. He didn't pray for the man's death. God is the Judge.
On very few occasions, an instant judgment may be delivered by God or the Celestial forces. And sometimes the verdict may be literally uttered by or through the mouth of the faith-liberated and love-soaked believer. A close look at God's dealings with humans show that such instances are very rare and "Justice" is always mingled with "Mercy". You cannot site such rare examples and run away praying everyday or every week for people to die! You have to understand the "operations of spirit" or the modus operandi of spirit - the divine spirit realm... AND TAKE NOTE: Such instant Judgment comes from God -
not someone randomly praying for disaster to strike another human being, who in actuality is a brother or sister...
A key guiding principle is seen in a question: "Where is love and forgiveness and divine purpose in this matter?" - whatever matter or situation that may be before you.
