What does the Bible say about Christ's promise to come for His people?

In John 14:3, Jesus reassures His disciples that He will return to gather His people, saying, "I will come again and receive you unto myself, that where I am, there you may be also." This promise brings hope to believers, indicating that their eternal destination is union with Christ in glory. The promise is not merely about a physical return but encompasses the assurance of eternal life and presence with Him. This promise is foundational in the faith, as it underlines the certainty that Christ will not leave His people forsaken but will instead bring them into His eternal kingdom.
