What is the significance of baptism in the context of Lydia's conversion?

In Acts 16:14-15, after Lydia's heart is opened by the Lord and she believes the gospel, her immediate response is to be baptized. This act of baptism not only signifies her faith in Jesus Christ but also acts as a public declaration of her commitment to Him. It is an essential outworking of her faith, illustrating that true belief results in obedience to Christ's commands. While baptism does not save, it is a vital expression of the believer's identity in Christ and affirmation of God's saving grace in their lives. For Christians, baptism represents a covenant sign of being united with Christ in His death and resurrection, affirming their place among God's people.
