“Sirs, what must I do to be saved?” And they said, “Believe in the Lord Jesus, and you shall be saved.” (Acts 16:30-31).
If you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved. (Romans 10:9).
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord. (Romans 6:23).
We have peace with God through our Lord Jesus Christ. (Romans 5:1).
Why do you call me “Lord, Lord,” and not do what I say? (Luke 6:46).
Not everyone who says to me, “Lord, Lord,” will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven. Many will say to me on that day, “Lord, Lord, did we not prophesy in your name, and in your name drive out demons and perform many miracles?” Then I will tell them plainly, “I never knew you. Away from me, you evildoers!” (Matthew 7:21-23, NIV).
