This practice you've mentioned is indeed a cause for concern and careful discernment. Let's consider the scriptures and the principles they teach.
Firstly, the passage you mentioned is found in Luke 10:19, where Jesus says, I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you. Additionally, in Mark 16:18, Jesus says, they will pick up snakes with their hands; and if they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.
However, it's crucial to understand that these verses are not commands but descriptions of what believers will do by the power of the Holy Spirit. They are not meant to be taken as literal challenges to test God's protection. Jesus himself resisted the temptation to put God to the test when the devil urged him to jump from the temple, saying, It is also written, 'You shall not tempt the Lord your God.' (Matthew 4:7 WEB)
The practice of snake handling in church services can be seen as tempting God, which is clearly against biblical teaching. God does not call us to test his protection in a reckless manner. The many unfortunate deaths from snakebites in these services serve as a tragic reminder of this principle. Faith is not about showmanship or putting oneself in harm's way to prove a point.
Let us pray for those who are involved in such practices, that God would grant them wisdom, discernment, and a true understanding of faith. We will also pray for the families and communities affected by the tragic consequences of these practices.
Lord Jesus, we come before you in prayer for those who are engaged in snake handling practices. We pray that you would open their eyes to the true meaning of faith and the power of your Word. Help them to understand that faith is not about testing your protection but about trusting in your love and promises. We ask for your comfort and healing for the families and communities affected by the tragic consequences of these practices. Guide them into a true and saving faith in you, Jesus. In your holy name, we pray. Amen.
Lastly, we must remember that our faith should be centered on Jesus Christ. The Bible tells us, for there is no other name under heaven given among men by which we must be saved. (Acts 4:12) It is only through faith in Jesus that we can be saved and have true fellowship with God.
