Discipleship is based on devotion to Jesus Christ, not on adherence to a belief or a creed.

From John 21:15-17:  “When they had finished breakfast, Jesus said to Simon Peter, ‘Simon son of John, do you love Me more than these?’  He said to Him, ‘Yes, Lord; You know that I love you.’  Jesus said to him, ‘Feed My lambs.’  A second time He said to him, ‘Simon son of John, do you love Me?’  He said to Him, ‘Yes, Lord; You know that I love you.’  Jesus said to him, ‘Tend My sheep.’  He said to him the third time, ‘Simon son of John, do you love Me?’  Peter felt hurt because He said to him the third time, ‘Do you love Me?’  And he said to Him, ‘Lord, You know everything; You know that I love you.’  Jesus said to him, ‘Feed My sheep.'”

Oswald Chambers (1874-1917) was a Scottish evangelist and Christian teacher.  Following his death from an illness while in Egypt during World War I, his wife took on the task of transcribing the detailed notes she had written from his lectures and sermons.  Gertrude Hobbs Chambers’ efforts resulted in the publication in 1924 of MY UTMOST FOR HIS HIGHEST.  I frequently read from this devotional, and it has greatly deepened my faith and understanding of God’s Word.
