What should Christians do when they feel heavy-hearted?

In moments of heavy-heartedness, the psalmist illustrates a pattern we should follow: recognizing our state and seeking God's help through His Word. 'My soul melteth for heaviness; strengthen thou me according unto thy word' shows that the psalmist does not stay in despair, but actively reaches out for support. Christians are encouraged to bring their burdens before the Lord, confessing their struggles and looking for His promise of strength and restoration. Isaiah 61 echoes this truth, affirming that God replaces mourning with joy, which is central to the believer's hope and faith.
