We should take seriously requests for prayer and figure out a way to fulfill that request. The good news is that there is no “formula” to intercessory prayer. In other words, most of the time you can’t get this type of prayer “wrong.” God hears our prayers, no matter how inarticulate we are in presenting them.
However, we can do a few things to more closely imitate Jesus and pray for someone with great diligence and care.
Often when someone asks us to pray for them, we say we will, but then quickly forget. That is why it is suggested to pray for them right away. This can be in your own words, or by praying a Hail Mary or Our Father for them and their intentions. A simple prayer like this is better than never praying for them at all.
Pray with your heart
As with all prayer, God loves to see us pray with our heart, not just our lips. It’s easy to voice a prayer of petition without any emotion tied to it, but it is much harder to take this petition into your heart and bring it before God with all sincerity.
