Cursing, foul language proceeding from our mouths and our hearts is a SIN against our God. It should not be named among the righteous. However, many persons are yet to overcome this work of the flesh. Our God will enable us to walk in victory if we make the right choice.

Psalm 51:9-10 King James Version (KJV)

9 Hide thy face from my sins, and blot out all mine iniquities.

10 Create in me a clean heart, O God; and renew a right spirit within me.
