Yet the mere presence of doubt does not deny faith. One cannot really believe what one has not doubted. Christians must help rstore wayward brothers and sisters. People drift from close, personal relationships with God and God's people. For the most part, followers of JC are satisfied with a life so conformed to the world, and so like it in almost every response, that to a casual observer there is no difference between the Christian and the pagan.
Believers have a responsibility to help other brothers and sisters.
Caught indicates ensnared or overpowered by sin, unlikely to escape without help. Spiritual means walking by the spirit. Restore has idea or returning to original state, mending net or resetting broken bone. While process may be painful, is process of restoration rather than punishment. We belong to God, purchased with price, redeemed.
