Prayer is not words. Its not flowery language. It is not King James Version. It is groans. It is unspoken words. It is the lament of a soul. It is sincerity. It is the longings, whether expressed or sighed. It is what God listens to. Real prayer does not need words. It is heart communicating to heart (Psalm 42: 7).
What words did Hannah use when she struggled in anguish? Read I Samuel 1: 13
