Also, Acts 10 tells us of a man named Cornelius who gave generously and prayed regularly but needed to hear about God's plan of salvation. His prayers and offerings, which were memorials to God, gave God cause to send an angel to him. The angel told him to send for a man named Simon (Peter-one of the twelve disciples.) Peter taught him about Christ and the forgiveness of sins. This lets us know we can raise a memorial to God for a specific purpose with our prayers and offerings.
