Psalm 16:8 – I have set the LORD always before me: because he is at my right hand, I shall not be moved.

Psalm 16:11 – Thou wilt shew me the path of life: in thy presence is  fulness of joy; at thy right hand there are pleasures for evermore.

By faith I can always be aware of God’s presence, even though my senses cannot perceive him. This continual awareness of His presence leads to unshakeable faith.
