The way of love is as true as the way of knowledge. All paths ultimately lead to the same Truth. But as long as God keeps the feeling of ego in us, it is easier to follow the path of love.
Only our love hath no decay; this, no tomorrow hath, nor yesterday, running it never runs from us away, but truly keeps his first, last, everlasting day.
Love does not fail for you when you are rejected, betrayed or apparently not Loved. Love fails for you when you reject, betray and do not love. Therefore .. Love.
