Please tell me the teaching of Jesus ( in English )

Go then, and make disciples of all the nations, giving them baptism in the name of the Father and of the Son and of the Holy Spirit: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Matthew 28:19-20

And you are to have love for the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength. The second is this, Have love for your neighbour as for yourself. There is no other law greater than these. Mark 12:30-31

Then do not be full of care, saying, What are we to have for food or drink? or, With what may we be clothed? Because the Gentiles go in search of all these things: for your Father in heaven has knowledge that you have need of all these things: But let your first care be for his kingdom and his righteousness; and all these other things will be given to you in addition. Then have no care for tomorrow: tomorrow will take care of itself. Take the trouble of the day as it comes. Matthew 6:31-34
