How important is prayer? The more you have to do the more you need to pray. We think we can do things on our own but we need God's power. We get this from prayer.
It is important to pray for others. Intercessory prayer is something God wants us to do. Someone may not be able to pray for themselves and need you to pray for them. If God brings someone t your mind, you need to pray for them. Sometimes they don't even realize they need prayer or possibly they are under attack by Satan.
The more we live God's way the more we can discern the needs of others. The closer we walk with God the more we see the needs we have in our own lives.
Prayer takes time. It can be easy to get so busy during the day that we forget to pray. You can pray when you are washing dishes, sweeping the floor, doing laundry or whatever work you have to do. My pastor says you can pray while driving; just don't close your eyes.
Prayer takes time and it takes energy and consentration. We need to keep our bodies healthy to be able to pray and do the other things we need to do.
If God has brought sickness into your life, ask Him what He wants you to learn from it. He has a lesson for you that you could not learn any other way.
