*Cry to me, and I will answer you, and I will teach you great and hidden things that you do not know.
Jeremiah 33: 3 New King James Version (RVR1960)*
God knows all our needs, and He likes us to cry out to Him. He only expects us to seek Him and to be attentive to His call.
The Bible is known as the mouth of God, it is He speaking to us through the Bible. So we have a thousand and one ways to communicate with God.
When he asks us to cry out to him, it is because God does not despise a humbled heart, rather, if we ask, he will show us great and hidden things that we do not know, since there will be mysteries everywhere that only he can answer.
So let's maintain a life of prayer, since God pleases a people who knows how to speak with Him.
