If you are saved, it's by grace as the gift of God. Grace is far more than a theological term or a religious song. Grace is God Himself. He is the God of all grace. Grace is undeserved favor that we can never earn nor merit. Grace alone is the gift of God, and not of our works (Ephesians 2:8-9).
If you are saved, it's by grace through the gospel (Romans 1:16). The gospel is the power of God changing your life through Christ our Lord. So many look to laws and rules to change people and society. The law may dictate how we should live, what we should do, or not do. Nevertheless, the law is powerless to change the hearts and lives of people.
If you are saved, it's by grace through regeneration of the Holy Spirit. That's your new birth (Titus 3:5). Grace changes you from within. Grace renews your mind, taking away the guilt of conscience, and renews your will to do God's good will. The law of God tells what you ought to be; the grace of God makes you what you ought to be.
If you are saved, it's by grace alone, as the gift of God in our Lord Jesus Christ. Grace gives you the unmerited favor of God through Jesus Christ. "And of His fullness we have all received, and grace for grace" (John 1:16). Receiving Jesus Christ is the fullness of grace to save us. Believing Christ is receiving Christ (John 1:11-12). God's grace freely saves you in Christ.
