Long ago God spoke to our ancestors in many and various ways by the prophets, but in these last days he has spoken to us by a Son, whom he appointed heir of all things, through whom he also created the worlds. He is the reflection of God’s glory and the exact imprint of God’s very being, and he sustains all things by his powerful word. When he had made purification for sins, he sat down at the right hand of the Majesty on high, having become as much superior to angels as the name he has inherited is more excellent than theirs. (Hebrews 1:1-4, NRSV)
In the early days God spoke through prophets to get His word to the people, but now He has spoken to us through the Son. He appointed Jesus to tell us all things so we may live with the word of God and see how we should live.
We now have a living example to see the way we should treat others.
Let us follow His example and live the love of God.
