It can be strange to hear that Europe and North America seem to be losing faith whereas other parts of the world, such as Africa and Asia are seeing incredible growth in the Church. Others have offered reasons; Scripture offers an explanation: suffering for the Lord.
In the west, we have religious freedom and far more than we need. While we have these wonderful blessings of God, I wonder if we have forgotten that our goal is not to find more things to enjoy, but to share the Good News of Jesus, to sacrifice for those in need and to remember that if we truly want to live a Christian life, then suffering for His Sake should be expected.
Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory. (Romans 8:17)
