It is a trustworthy saying and deserving full acceptance: that Christ Jesus came into the world to save sinners, among whom I am foremost.

-1 Timothy 1:15 (LSB)

For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures, and that He appeared to Cephas, then to the twelve. After that He appeared to more than five hundred brothers at one time, most of whom remain until now, but some have fallen asleep. After that, He appeared to James, then to all the apostles,

-1 Corinthians 15:3-7 (LSB)

It is a trustworthy saying:

‎ ‎ ‎ ‎ For if we died with Him, we will also live with Him;

‎ ‎ ‎ ‎ If we endure, we will also reign with Him;

‎ ‎ ‎ ‎ If we will deny Him, He also will deny us;

‎ ‎ ‎ ‎ If we are faithless, He remains faithful, for He cannot deny Himself.

-2 Timothy 2:11-13 (LSB)

No one can say, “Jesus is Lord,” except by the Holy Spirit.

-1 Corinthians 12:3 (LSB)

Christ Jesus, who, although existing in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, by taking the form of a slave, by being made in the likeness of men. Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross. Therefore, God also highly exalted Him, and bestowed on Him the name which is above every name, so that at the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth, and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father.

-Philippians 2:5-11
