Why is believing in God's everlasting love important for Christians?

The belief in God's everlasting love is foundational for Christian faith as it assures believers of their eternal security. Jeremiah 31:3 highlights this profound truth by stating, 'I have loved thee with an everlasting love.' This understanding reinforces the doctrine that God's love is not based on human merit but is freely given. It is this love that motivates the believer's relationship with God, allowing them to rest in the assurance that they are forever secure in His grace. Knowing that one's name is written in the Lamb's Book of Life provides deep comfort and motivates a life of worship and service in gratitude for such unmerited favor.
