In times of adversity Satan will seek to plant the thought in our minds that God is angry with us and is disciplining us out of wrath. Here is another instance when we need to preach the gospel to ourselves. It is the gospel that will reassure that the penalty for our sins has been paid, that God's justice has been fully satisfied. It is the gospel that supplies a good part of the armor of God with which we are to stand against the accusing attacks of the Devil (see Ephesians 6:13-17).
