Why do we need a mediator in our relationship with God?

In the context of salvation, a mediator is essential because sinful humanity cannot approach a holy God without an intermediary. Jesus Christ fulfills this role as the perfect mediator, as described in 1 Timothy 2:5, where it states that there is one mediator between God and men, the man Christ Jesus. His atoning work on the cross is what reconciles us to God, addressing the gap created by sin. As our advocate, He pleads our case before the Father, ensuring that those who believe in Him have their sins forgiven and are accepted into God’s presence.
