Philemon 1:7 Your love has given me great joy and encouragement, because you, brother, have refreshed the hearts of the saints. God uses people to refresh the hearts of Christians. There are so many verses that say we should build each other up with our words, that we should love each other in word and deed. And just like in this image of smiling hearts getting rained on, God cleanses and refreshes our hearts with His word. It's also a cute Valentine's Day image for kids.
