How do we know Jesus is a source of comfort?

In John 14:1, Jesus commands His disciples not to let their hearts be troubled, instead directing them to believe in Him just as they believe in God. This illustrates Jesus' role not only as a savior but as a personal source of comfort. The context of this passage reveals that, despite impending trials and suffering, He assures His followers of His unwavering presence and the promise of a prepared place for them in heaven. This promise underscores His commitment to their eternal well-being, inviting them to cast their anxieties on Him.
