Our ultimate purpose is to glorify God, that is, to show forth His greatness and supremacy (1 Corinthians 10:31), as we magnify Christ in all things (Philippians 1:19-20). Christ is the ultimate revelation of God (Hebrews 1:1-3) and so we do not glorify the Father without glorifying the Son (John 5:23).
It is those who follow or obey Christ who glorify Him and the Father (John 15:1-10) and such followers, like their Savior, have great joy (John 15:11; Hebrews 12:2). That joy magnifies Christ (Psalm 100; Philippians 1:19-23).
Since our ultimate purpose is to glorify Christ, it is imperative we come to know Him (John 17:30) and continually grow in our knowledge of Him (2 Peter 3:18). The more we grow in our knowledge of our Lord and Savior, the more we want to follow Him.
The more we follow Jesus, the more we want to grow to be like Him (1 Corinthians 11:1; 2 Corinthians 3:18; Philippians 2:5-11).
The more we become like Jesus, the more we want to serve Him and others to the glory of God (1 Peter 4:10-11, 19).
The more we want to serve Christ, the more we will want to share Him with others in such a way that we are disciples (followers) of Jesus Christ who make other disciples (Matthew 28:19-20; 2 Timothy 2: 2). The vision we have is to equip disciple makers for all of life (family, work, friends, neighbors).
