Colossians 3:14 Above all, clothe yourselves with love, which binds us all together in perfect harmony.
15 And let the peace that comes from Christ rule in your hearts. For as members of one body you are called to live in peace. And always be thankful.

Every child of God has the capacity to love, Paul here is saying that you can express God's love to everyone around you. God's love is the binding cord among believers, and this is not an  eye service thing, it's from the core of our spirit. Because we are born of God, we have what it takes to love, this love produces peace beyond words in our heart.

Unless you love your fellow believers, walk in love towards them, you may not experience peace that make us enjoy fellowship with one another. The beautiful thing is that we all have capacity to walk in love towards one another because we are born of God and God is love.

I John 4:7 Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God. 8 He who does not love does not know God, for God is love.

This is so amazing, everyone who is born of have the capacity to love. Anyone who refuses to walk in love is considered an outcast in God's Kingdom. You have to exercise yourself in God's love towards others. Walking in love towards other does not mean that they would reciprocate the same to you, but you must choose to walk in love towards them irrespective.

1 Corinthians 13:5...and it keeps no record of being wronged.
