Acts 1:15-17,20-26; Psalm 112(113):1-8; John 15:9-17
I call you friends, says the Lord...
because I have made known to you everything that comes from the Father.
So - this life is all about relationship - and a living relationship of Love, that Jesus has enabled us to share in. Like all relationships this takes work (on both sides). We can be sure that God will be working for us, we need to ensure that we do our part. Jesus makes very clear using a repetition (v 12 and v17) to reinforce the message, that what we are asked to do is to love one another.
We are reminded of the message from Mk 12:28 in which Jesus is asked - 'which is the greatest commandment' - and in his extended answer, Jesus makes clear that if we love one another as God loves us, then none of the other commandments really matter, as we would become incapable of breaking them in any case.
