In principle you can ask anything, but there is a condition that you do not ask for things just to satisfy your own selfish needs. Fortunately, God comes to the rescue of our weaknesses because we do not know what to pray as it should. However, He guides us by His Spirit. You should pray a prayer that Jesus himself could pray too. That is what it means when you pray in Jesus’ Name. James 4: 3, Romans 8:26, John 15:16
