How is eternal life obtained according to the Bible?

According to Titus 3:4-7, eternal life is obtained through the kindness and love of God our Savior, who saved us not by our works of righteousness, but according to His mercy. This emphasizes that salvation is a gift that cannot be earned or deserved by any human effort. It is through the washing of regeneration and the renewing of the Holy Spirit that believers are made heirs to the hope of eternal life. This gracious act of God assures believers that their standing before Him is secure, based on faith in Christ alone.
