Why is it necessary to stay in the city of refuge?

In Numbers 35, the manslayer was required to stay within the city of refuge to avoid the revenger of blood. This necessity parallels the believer's life in Christ; those who have fled to Him must remain steadfast in their faith. The sermon highlights that initial fleeing to Christ is not the end; perseverance in faith is required. Various Scripture, including Colossians 1:22-23, reinforces that maintaining one's standing in Christ is essential for salvation, as true believers will endure and remain securely in Him.
