And surely I am with you always, to the very end of the age. (NIV)
Occasionally this verse is used to prove the Trinity because it is said that the only way that Jesus could always be with his Church is if he were God. However, that is an unproven assumption, and is not stated in Scripture. Scripture shows us that there is a use of “with us” that is spiritual in nature, not physical. We must be careful not to underestimate the power and authority God gave Christ when He set him at His own right hand and gave him a name that is above every name. Just two verses before this one, Christ said he had been given “all authority.” God gave Christ all authority, and made Christ Head of the Church, so it is only logical to conclude that God also gave Christ the power to stay in communion with his Church.
