Of first importance is "..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 bretheren at one time, most of whom remain until now, but some have fallen asleep; then He appeared to James, then to all the apostles;.."
(1 Cor. 15:3-7)

and that,...
"...no prophesy of Scripture is a matter of one's own interpretation, for no prophesy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God."
(2 Peter 1:20-21)

and that,...
"There is one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all."
(Ephesians 4:4-6)

and that,...
"..He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ; until we attain to the unity of the faith..."
(Ephesians 4:11-13)

"That with one accord you may with one voice glorify the God and Father of our Lord Jesus Christ."
(Romans 15:6)

and that while we are in the world we are called to,...
"...love one another, even as I (Jesus) have loved you, that you also love one another."
(John 13:34)

and that we have a joyful hope,
"For the Lord Himself will descend from heaven with a shout, with the voice of the archangel, and with the trumpet of God; and the dead in Christ shall rise first. Then we who are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air, and thus we shall always be with the Lord."
(1 Thessalonians 4:16-17)
