We know it by Spirit he give us, love one another

1 John 3:11-24
We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death.
This is how we know what love is: Jesus Christ laid down his life for us. 
If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? 
Dear children, let us not love with words or speech but with actions and in truth.
If our hearts condemn us, we know that God is greater than our hearts, and he knows everything.
And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. The one who keeps God’s commands lives in him,and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
The message 'heard from the very beginning' is that God's people must love one another. What does that mean? John tells us plainly: "This is how we know what love is: Chirst gave his life for us!" This love is not just talk. It expresses itself in sacrifice and self-giving. And it will touch our pockets! If our conscience is clear on this score, we can approach God with confidence. He answers the prayers of those who obey him.
God commands us to believe that the Jesus of history is in fact the Son of God, the Christ - and to love one another as Jesus commanded. Those who do so 'live in him and he in them'. We know it by his gift of the Spirit.
Why?
Love one another is not love with words or tongue, but with actions and in truth. It means will touch our pockets. 
We know these from the beginning we know it by the Spirit. So when we do love it, and our conscience is clear then we know we have approached it.
How?
Love one another with actions. For Jesus laid down his life for me!
