A purified heart

D&C 88:74

I like it how it says in this scripture how we are supposed to assemble and ourselves. In other words we are supposed to gather to together to become prepared, and to become clean. This applies to every week when we go to church to partake of the sacrament and to be organized into callings, and we become prepared for the upcoming week. This is necessary so we can become clean so we'll be more in touch with the Spirit when going forth to preach the gospel.
