"But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him."
1 Corinthians 2:9
I love the mystery gift idea here. The unknowing in context seems to suggest that the gift is beyond words... so great that we can't really comprehend it. "Worth the effort" seems accurate, but inadequate, because who we become through obedience to God and getting his advice and help is already worth it... I think stunning, beyond measure, perfect, ultimate happiness is probably closer, but still not even scratching the surface.
Today, let's trust in the mysterious abundance that God has in store.
