It has divine appointments for the fulfillment of its great commission. Each believer is born of the Spirit and is an integral part of the Church of the Firstborn. The Ordinances of the Church. The ordinance of baptism by immersion in the name of the Father, and of the Son and of the Holy Spirit is commanded in the Scriptures. All who repent and believe in Christ as Savior and Lord are to be baptized.
Sanctification is two things.
It is an initial act that God performs when he saves us and it is an ongoing process. Initially God cleanses us from sin and picks us to be holy. Then we must live a holy life each day in a sinful world. The more we allow the Holy Spirit to control our choices the less we fall into sin. This is our part in the process of sanctification.
