What does the Bible say about mediation in salvation?

In the Old Testament, we see Moses serving as a mediator between God and Israel, as described in Exodus 19:3-6. This pattern points to Jesus Christ, who fulfills the role of mediator perfectly. Without a mediator, there is no means for sinful humanity to approach a holy God, highlighting our need for Christ, who intercedes on our behalf (Hebrews 7:25). The necessity of mediation underscores our dependence on God's grace for salvation and the relationship we have through Christ with the Father.
