Memory offering: give generously to those in need and prayed to God regularly

Acts 9:43-10:8
Cornelius he and all his family were devout and God-fearing; he gave generously to those in need and prayed to God regularly.
God gave Cornelius a vision and called him to invite Peter to him. Angel answered, "Your prayers and gifts to the poor have come p as a memorial offering before God."
Why?
Up to this point the gospel has been preached only to Jews, converts to Judaism and Samaritans(who observed the law of Moses). Now God steps in to make it plain that the message is for everyone, God prepares the Roman officer, Cornelius, and he prepares Peter.
Cornelius, a centurion: One of those who formed he backbone of the Roman army. The centurions stationed in Palestine appear in a very favorable light in the New Testament. Cornelius was an adherent to Jewish faith and worship, but not a circumcised convert.
God chose those who is devout and God-fearing. Who give generously to those in need and prayed to God regularly.
Do I have the passion to be a instrument of the Lord? Then be a devout and God-fearing one.
Memory offering is best offering to the Lord in these generation. Do the right thing for the Lord!
How?
Give generously to those in need and prayed to God regularly, then God will like this one.
