But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us. (Romans 5:8)

"Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven." (Matthew 7:21)

"If you love Me, keep My commandments." (John 14:15)

And having been perfected, He became the author of eternal salvation to all who obey Him. (Hebrews 5:9)

Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, by which also you are saved, if you hold fast that word which I preached to you; unless you believed in vain. For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures.
(I Corinthians 15:1-4)

Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life. (Romans 6:4)
