1 John 5:2-4 New International Version (NIV)
This is how we know that we love the children of God: by loving God and carrying out his commands. In fact, this is love for God: to keep his commands. And his commands are not burdensome, for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith.
God's commands are easy and by keeping his commands, now that is how the children of God show their love for God. Now is there a command against witchcraft? During the time of the Israelites, God gave this command:
Deuteronomy 18:10-11 New International Version (NIV)
Let no one be found among you who sacrifices their son or daughter in the fire,
who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead.
How about for the true Christians? Did God allowed witchcraft? Did His decree changed?
Galatians 5:19-21 New International Version (NIV)
The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and
witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that
those who live like this will not inherit the kingdom of God.
But personally, I used to sing a song about witchcraft.
And that was a long time ago.
