From Come Follow Me this week is a solid explanation of a passage that caused us difficulty on the mission. I remember Elder Davis explaining (in one of the more Catholic areas of our mission) how he would NEVER teach with these passages because it was too hard to deal with entrenched Trinity-believers. Come Follow Me seems to do a good job untangling this issue.
These passages are sometimes confusing because it can seem that Abinadi is teaching that Heavenly Father and Jesus Christ are the same Being, yet we know that they are separate Beings. What did Abinadi mean? He taught that God the Son– Jehovah–would be the Redeemer (see Mosiah 15:1), dwelling in the flesh, becoming part man and part God (verses 2-3). He completely subjected Himself to the will of God the Father (verses 5-9). Because of this, Jesus Christ is both the Son of God and the perfect earthly representation of God the Father (see John 14:6-10).
The pictured Come Follow Me text is from the version described here.
