What is prayer? The simple answer is this: prayer is having a conversation with God. Conversation is a part of any vital and growing relationship. We sometimes measure the quality of a marriage relationship by how well the couples communicate. Or to state it another way, one of the first things people point to as evidence that a marriage is in trouble is a lack of communication. The same is true for our relationship with the Father. True, honest, heartfelt conversation is a sign of a healthy relationship. A lack of conversation, or conversation only in public is a sign of a relationship in trouble.
Prayer is a privilege purchased by the blood of Jesus Christ. Christ died for this end, it cost him the shedding of his blood, so that we, through him, might have entrance to the throne of grace. And will you let such a privilege as this lie still? If you do, so far as is in you, you cause his blood to be shed in vain. For if you neglect the privileges gotten by that blood, you neglect the blood that procured them.
