9 As the Father hath loved me, so have I loved you: continue ye in my love.
10 If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
11 These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.
The LORD JESUS has assured us that because THE FATHER LOVES HIM and he loves us (AND GAVE his life FOR US) AND he WANTS US TO CONTINUE BY BEING OBEDIENT TO him, IN his love EVERY DAY WE ARE HERE ON PLANET EARTH...
He ASKS us TO DO WITH him WHAT he HAS done WITH GOD the Father... KEEP HIS COMMANDMENTS. CONTINUE to ABIDE IN HIS LOVE..
WHY did HE tell us these things?
SO that HIS JOY might remain IN US and that OUR JOY would would be FULL !!!
Christians should be JOYOUS alway! We have MUCH to be joyful about!!!
