Why is the concept of Immanuel significant for Christians?

The name 'Immanuel,' which means 'God with us,' is a profound concept for Christians because it encapsulates the reality of God's presence in the world and in the lives of believers. This truth is foundational, as it assures us that God is actively involved in human affairs and has not distanced Himself from our struggles. The incarnation of Christ, described in Matthew 1:23 and Isaiah 7:14, assures us that through Jesus, God has personally entered into human history to bring salvation. This presence provides comfort and encouragement in trials, reinforcing the promise that God never leaves nor forsakes those who trust in Him. For believers, Immanuel symbolizes the hope and assurance that they are never alone, as their Savior walks alongside them, guiding and sustaining them.
