Yes, four gospels of our Lord and Saviour Jesus Christ. In Jesus gospel we are told things such as:

Matt 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. 19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

Matt 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life? 17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. 

1 John 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
(no body wants to teach this one now, do they?)

John 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.

Matt 6:14 For if ye forgive men their trespasses, your heavenly Father will also forgive you: 15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.

These are among the testimony and gospel of Jesus Christ. If you believe on Jesus as your Lord and saviour, then are you not expected to teach and do that which he commanded us?
