Ephesians 3:19 and to know this love that surpasses knowledge – that you may be filled to the measure of all the fullness of God.
The closer we get to God, the better our relationships with others get, not because they are Christians as well, but because we try to live by God's love in our lives!
God wants us to share this love Christ shared with us – we need to draw on this love in everything we don in our lives.
We may not be able to understand the depth of Christ's love for us, but if we aim to have that love with others, life would be so much better for all!
