We are told quite a few incredible things in John 10. It communicates basic principles about churches today, and what we need to keep in mind about them. The first verse reads as follows:
“I ASSURE you, most solemnly I tell you, he who does not enter by the door into the sheepfold, but climbs up some other way (elsewhere, from some other quarter) is a thief and a robber.” John 10:1
Later on in the chapter Jesus refers to Himself as the Door, so I want to use that declaration when explaining verse 1:
“So Jesus said again, I assure you, most solemnly I tell you, that I Myself am the Door for the sheep.” John 10:7
I want to apply these two verses to churches today. If a preacher approaches his flock from any angle other than Jesus (and what He accomplished/represents), he is a thief and a robber. That means any teaching that does not reflect Jesus and what He has accomplished is false. That means you cannot read a verse from the Old Testament without first putting it into context with the death and resurrection of Jesus.
Jesus came to change a whole bunch of things – we simply cannot exclude what He has done from any teaching. That is also why Paul said the following:
“For I resolved to know nothing (to be acquainted with nothing, to make a display of the knowledge of nothing, and to be conscious of nothing) among you except Jesus Christ (the Messiah) and Him crucified.” 1 Cor 2:2
