Quote of the Day

“Blessed are those that trust in the Lord... They are like trees planted along a riverbank, with roots that reach deep into water. Such trees are not bothered by the heat or worried by long months of drought. Their leaves stay green, and they go right on producing delicious fruit. - Jeremiah 17:7-8”
