You cannot have that without a rooting into Jesus Christ. You cannot expect to be part of the church unless you have been taken out of Christ's death. God's natural resource is Christ's death. The lily drawing from the strength of the soil it is planted in is a picture of how we grow, by being planted into Christ's death, and drawing from His nature through our unions to His death. What we have faith in for our desire to be part of the real church and go to Heaven is what we feel will make that happen.
Some people trust in their good deeds.
Some in their family's church no matter what church it is as long as it is their family's church. None of that is what God takes to make His church. There is only one thing we can have faith in if we want to be part of the church. Some have faith in that partly, but also depend, with for the remainder of their faith, in deeds and traditions of their families. Their faith is divided between the true and the false.
