This text teaches us that God loved the world in this way: that he gave his only Son, Jesus Christ, that whoever believes in him should not perish but have eternal life. He demonstrated his love for us through his self-sacrifice and calls his followers to show the world the way in which God loves the world through our own sacrifice. This is why sacrifice and faithful discipleship are inseparable. God's love is a love that costs; a love that offers salvation, and we are heralds of this message of good news to the world. What is the sacrifice God is requiring of us today?
