Before we nullify a curse, it is helpful to test our hearts and repent if we have more love for ourselves than for God. There is little point in breaking a curse if we don’t love God solely for who He is, rather than what He can do for us. We should not use His name in vain, to benefit ourselves. Otherwise, we will still live as accursed.
1 Corinthians 16:22 ESV If anyone has no love for the Lord, let him be accursed. Our Lord, come!
