Sin can make you feel full but only for a small time and will soon leave you with an empty feeling. Hunger is the English word for starvation. Thirsty will leave your lips cracked and hurting. Does hunger & thirst leave you? No, you are continually hungry and thirsty and so goes for the word. When we sped time with God we have an extraction of what is rooted deep inside and needs to come out. God is looking for those that are serious, hungry and thirsty!
