What is the significance of being a saint in Christianity?

In Christian theology, a saint is defined not by actions or titles bestowed by church authorities but by the inherent belief in the Lord Jesus Christ. As per Colossians 1:2, believers are called 'saints' because they have been set apart for God’s service. This concept stems from the understanding that saints are those who have received God's grace and are now living in accordance with His will, characterized by their faith and transformation through the Holy Spirit. This title embraces every true believer, highlighting their identity as part of the universal Church and as inheritors of God's promises.
