Pray for yourself. Pray for our church, pray for the pastor. And don't stop praying until you understand the answer God had in store for you all along. One final thing when you are dealing with a person who is questioning and struggling and having a hard time believing and committing. Let them know you struggle sometimes too.
Every warrior comes back from the battlefield of life scarred, bruised and broken sometimes.
God's armor just keeps you alive, it doesn't keep you from getting hurt. If you share your doubts with the doubter, along with your faith, maybe they will know that you are more like a brother or sister to them then they had imagined. And that God is the One who grabs a hold of us, slowly makes things clear and gives us the gift of faith.
