"Men ought always to pray" Luke 18:1
I have a question to offer you. It is contained in three words, do you pray?
The question is one that none but you can answer. Whether you attend public worship or not, your minister knows. Whether you have family prayers in your house or not, your relations know. But whether you pray in private or not, is a matter between yourself and God.
