Just as the title indicates, this famous booklet of St. Alphonsus Liguori teaches us how to speak personally and with confidence in prayer to God, who, the Saint says, will not speak to us unless we first speak to Him. Covers every aspect of our personal relationship with God. St. Paul says of Our Lord, In whom we have boldness and access with confidence by the faith of him.(Ephesians 3:12). Thus, we can approach God as His friends, with confidence and boldness! But that is how God wants us to be - familiar, confident, bold and constant!.
