What does the Bible say about God's love casting out fear?

In 1 John 4:18, we read that 'perfect love casts out fear.' This refers to mature love, particularly the love that God has for us. Many Christians struggle with fear because they have not fully grasped the depth of God's love for them. Our understanding of love is often shaped by human experiences, where love can be fickle and conditional, but God's love is steadfast and unconditional. By comprehending God's mature love, believers can experience a peace that alleviates fear, knowing that God is sovereign and in control of all things.
