Romans 1:16-17

“For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes for the Jew first and also for the Greek. For in it the righteousness of God is revealed from faith to faith; as it is written, “The just shall live by faith”.”

Ephesians 1: 13

“In whom you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise.”

NKJV
