What should Christians do in times of unbelief?

In times of unbelief, Christians are encouraged to cry out to God just as the father of the boy possessed by a spirit did, saying, 'I believe; help my unbelief!' (Mark 9:24). Prayer is pivotal in fortifying one’s faith, allowing believers to communicate their struggles directly to God. Believers should also immerse themselves in Scripture, which serves as a reminder of God's faithfulness and the historical evidence of His promises. Regular fellowship with other believers can provide support and encouragement, helping to align one's perspective with God's truth, thus combating the lies of doubt and fear.
