I have set the LORD always before me: because he is at my right hand, I shall not be moved. Psalms 16:8
The psalmist so deeply depends on the Lord for strength and joy that he senses God is right beside him. In David's eyes, God was not just an imaginary being but a Person actually at his side. In biblical times, the right hand was the most distinguished position, reserved for one's chief adviser and supporter. When we choose to focus on Christ we invite Him to take the most important position in our life as counselor and defender.
When we set the Lord always before us we choose to relate everything we encounter to our trust in God. Regardless of the battles we may face, He is our strength. With Him by our side we will not be shaken. There are many things that can trouble our lives but none can shake us loose from the grip of God's grace if our hearts remain pointed at Jesus our Lord. We can rest in complete assurance that He is with us in all situations.
