The Bible says, “The peace of God which surpasses all comprehension shall guard your hearts and your minds in Christ Jesus” (Phil. 4:7).
In other words, God has designed the Christian life to give Christians victory over the tyranny of their circumstances and the problems they face. Unfortunately, many true Christians do not experience this peace God wants them to have.
Peace comes when you realize that your burden is for God and not for you. Trying to use your mortal capacity to push through is what frustrates most Christians.
There is peace and contentment in serving God.
