Broken Spirit

"The sacrifices of God are a broken spirit,
A broken and a contrite heart—
These, O God, You will not despise." Psalms 51:17

God can only fill one with His Spirit when one empties oneself. He doesn't require perfection or holiness, but surely humbleness to recognise one's dependence on His guidance.

Living Waters

"He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water." John 7:38

The belief in Jesus also involves convenant, marriage, unconditional surrender of one's life, in other words, commit to the faith in Him above any circumtances. That is, with material blessings or not. Unfortunately, most of those who say they believe in Him, in truth, only believe in His existence - nothing else. When your belief is sincere, it's like a river that flows living waters.
