Love the Lord your God
with all your heart
and with all your soul and with all your mind.
This is the first and greatest commandment.

(Matthew 22:37-38 NIV)

And the second is like it:
Love your neighbor as yourself.
All the Law and the Prophets
hang on these two commandments.

(Matthew 22:39-40 NIV)

Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.

(Matthew 28:19-20 NIV)
