If you neglect your love to your neighbor, in vain you profess your love to God; for by your love to God, the love to your neighbor is begotten, and by the love to your neighbor, your love to God is nourished. --Francis Quarles
1 Peter 1:22-23, Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
Love is truly expressed when one has been touched by the love of God. Prior to salvation we did not love our spouses, children, or the world the way we ought to. Yes, we loved them but not with the same love that God has expressed toward us. He loves us unconditionally and sacrificially.
Have you been touched with the love of God? Do you know what it means to be loved by God? He is the reason we can love!
