You even celebrate certain days, months, seasons, and years. Galatians 4:9-10
Our parents, grandparents and families taught us to keep certain customs and traditions which have us enslaved, to the point where we give more importance to those than to the Word of God.
Christ set us free from all those customs and traditions imposed by men, and we should not keep on participating in such. Our parents taught those to us out of ignorance, but we must break away from that lie and declare that we are free to do his will. That way we will make it inoperative over our generation, the spirit which carries curse.
Let us not allow darkness to keep moving over us. Let us allow the Holy Spirit to reveal the truth to us and take us out into the light. Heaven is not subject to dates; it is subject to the Word. Let us seek revelation, which will take us through the ways of light and not of darkness.
