How do we know Christ is the ladder connecting heaven and earth?

In John 1:51, Jesus refers to Himself as the ladder set between heaven and earth, indicating that through Him, all blessings from God flow to humanity and vice versa. The imagery in Genesis 28, where Jacob dreams of a ladder with angels ascending and descending, is fulfilled in Christ. He is the only mediator between God and man, as seen in 1 Timothy 2:5. No one can approach God without the access granted through Christ, who spans the gap between the holy God and sinful humanity. Thus, He is indeed our only means of connection to the Father, providing intercession and bringing the blessings of heaven to earth.
