Why can't we approach the altar without a mediator?

The sermon emphasizes that the altar represents a sacred space where God’s holiness is underscored, and without a mediator, any attempt to approach leads to dire consequences, as shown in Numbers 18. The priests and Levites were strictly forbidden from approaching certain areas of the sanctuary. This highlights the necessity of a mediator, which, in the New Testament, is fulfilled by Jesus Christ. As our High Priest, He intercedes and allows believers to approach God, having died in our place and satisfied the demands of the law. This principle is essential to understanding the nature of salvation and the relationship between God and humanity.
