"God tells us to expect trials. It is not 'if you fall into trials,' but 'when you fall into trials.' The believer who expects the Christian life to be easy is in for a shock. We cannot always expect everything to go our way. Some trials come simply because we are human - sickness, accidents, disappointments, even seeming tragedies. Other trials come because we are Christians. Satan fights us and the world opposes us, resulting in a life of battle." (NKJV Wiersbe Study Bible)
