New Defender's Study Bible Notes
3:20 at the door. Compare Matthew 24:33; Revelation 19:9. When we see the signs of His imminent coming all around us, including many neutralist Laodicean-type churches, we know that He is at the door, about to come in, as it were, soon to sit down with all His saints at the great marriage supper of the Lamb.
3:20 come in to him. Although it is often used as such, this verse is not a gospel verse, appealing to the unsaved to accept Christ. There is nothing in it about Christ’s sacrificial death for sinners or about believing on Him for salvation, or any other gospel essentials. It is addressed directly to the neutralist, self-satisfied Laodicean church, calling them to repentance. In context, the Lord is calling worldly, compromising believers to allow Him back into their lives.
