Isaiah 58:10 "And if you draw out thy soul to the hungry, and satisfy the afflicted soul; then shall thy light rise in obscurity and the darkness around you will be as bright as the noonday."
The LORD isn't asking us to "feed the hungry with just physical food. He is asking us to draw from our soul and give to the hungry. It's certainly much easier to hand someone some change or a McDonald's gift certificate and feed their hungry mouths. But that won't meet the need of the hungry soul.
Only the Bread of Life, Jesus, can truly satisfy. As we decrease and allow Jesus to increase. His light shines brighter through us...lighting the darkness all around us...bringing hope.John 6:35 "And Jesus said unto them, I am the bread of life: he that comes to me shall never hunger; and he that believes on me shall never thirst."
Giving spiritual food to others will not only meet their spiritual need, but it will continually meet ours too. Have you experienced that? You are sharing the Word of God with someone and as the Word leaves your mouth, you hear it in your own ears and it waters you own life...your soul. Isaiah 58:11b "...You will be like a well-watered garden, like an ever-flowing spring."
Funny how that works, when we give, we receive back - if we give with the right motives, with the right heart.
