False.
St. John wrote not to unbelievers, but to believers who were part of the congregation in Laodicea (Revelation 3:14). Christ had ALREADY come into the Laodiccean believers through His powerful Word, but then they pusshed Him back out when they became "lukewarm, ...neither hot nor cold" (Revelation 3:16). These Christians become so preoccupied by the cares and affairs of their daily lives that
they pushed Christ out of their hearts and minds. The became "wretched and miserable and poor and blind and naked" (Revelation 3:17), even though they did not know it.
Because these believers had become lukewarm, Jesus said to them: "Behold, I stand at the door and knock: if anyone hears my My voice and opens the door, I will come in to him and will dine with him and he with Me" (Revelation 3:20). This verse does not speak about how you
become a Christian, as if you must first ask Jesus into your heart in order to be saved. This verse shows what happens when Christians throw Jesus out of of themselves by replacing Him with worldy preoccupations. Christ faithfully calls them to repentance through His Word so that He may enter them again.
