How do we know God is the one who gives life to believers?

According to Scripture, God is the one who gives life to believers through the Holy Spirit. Jesus explicitly states in John 10:10 that He came so that His followers may have life. This theme is echoed in 2 Corinthians 5:17, where Paul asserts that those who are in Christ are new creations, indicating a divine act of regeneration. Just as God breathed physical life into Adam, He breathes spiritual life into His people, calling them from spiritual barrenness to fullness in Him. This transformation is an example of God's sovereign grace, affirming that He alone initiates salvation and imparts life.
