Why is knowing God's presence important for Christians?

In Psalm 16:8, David declares, 'I have set the Lord always before me; because he is at my right hand, I shall not be shaken.' The recognition of God's unwavering presence brings comfort and confidence to believers. God's presence dispels fear, reassures us of His sovereignty, and allows us to navigate life's challenges with the assurance that He is with us. Moreover, knowing that we are in His presence brings us joy, as David states in verse 11, 'In your presence there is fullness of joy.' This joy is critical for Christians as it sustains us during trials and fosters a deeper relationship with God.
