How do we know God's love drives away fear?

The message of God’s love is central to the Reformed theology that embodies how sinners find refuge from fear. Perfect love, which stems from God alone, assures believers that they are not forsaken. The scripture states, 'Perfect love casteth out fear' (1 John 4:18), indicating that understanding and experiencing God’s affection serve as a profound remedy against anxiety and dread. When believers comprehend that Christ bore their sins and possesses an eternal capacity to forgive, fear dissipates, replaced by a confident assurance in His providential care over their lives.
