Jesus teaches the two Greatest Commandments in Mark 12:29-31 where the first emphasizes on one’s relationship with God and the second, emphasizes on one’s relationship with others. These two commandments indicate the outcomes for spiritual formation as one becomes more like Jesus (Tang, 2014). The first greatest commandment comes from the Shema of Judaism where it is the “Jewish creed of spiritual formation” (McKnight, 2004, p. 6). The declaration of “the Lord is one” in Mark 12:29 is a declaration not only for monotheism but also a recognition of the wholeness or oneness of God (McConville, 2002). The worshippers of God must have the same wholeness or integrity when they come before God in worship. Spiritual formation will enable one to come before God with the wholeness and integrity of heart, soul, mind, and strength as required in the first commandment of Christ. The second greatest commandment is a requirement for believers to love their neighbors as themselves. Believers can only express healthy love to their neighbors when they truly know how to love themselves as God’s chosen people formed by the Holy Spirit. Therefore, spiritual formation is the ongoing process where believers learn and develop right relationships with God, self, and others as they are formed spiritually to act and behave in Christ-likeness. When believers live in Christ-likeness, they will attain the goals of spiritual formation as a natural part of their godly and transformed lifestyles.
