In Christ there is neither male nor female. We are all told to present our bodies as living sacrifices to God (see Rom. 12:1). Never let anyone convince you that women shouldn’t be actively involved in the Great Commission. When we each appear before the Lord, none of us want to be empty-handed; we want to bring as many people as possible into the Kingdom.
Deuteronomy 16:16 “Three times a year all your males shall appear before the Lord your God in the place which He chooses: at the Feast of Unleavened Bread, at the Feast of Weeks, and at the Feast of Tabernacles; and they shall not appear before the Lord empty-handed.
