What does it mean that Christ gives abundant life?

In John 10:10, Jesus contrasts the thief's purpose of stealing and destroying with His mission of coming to bring life, 'that they might have it more abundantly.' This abundant life signifies more than mere physical existence; it encompasses spiritual vitality, peace, hope, and joy that transcends earthly troubles. The Reformed understanding asserts that this life is a gift from God, throbbing with the richness of grace and the assurance of eternal security for the believers. Therefore, abundant life in Christ represents a transformed existence, where every believer walks in the light and fullness of His salvation.
