I have set the LORD always before me: because he is at my right hand, I shall not be moved.
The certainty that God is always near us, present in all parts of His world, closer to us than our thoughts, should maintain us in a state of high moral happiness most of the time. But not all the time. It would be less than honest to promise every believer continual jubilee and less than realistic to expect it. As a child may cry out in pain even when sheltered in its mother’s arms, so a Christian may sometimes know what it is to suffer even in the conscious presence of God. Though “alway rejoicing,” Paul admitted that he was sometimes sorrowful (2 Corinthians 6:10), and for our sakes Christ experienced strong crying and tears though He never left the bosom of the Father (John 1:18).
But all will be well. In a world like this tears have their therapeutic effects. The healing balm distilled from the garments of the enfolding Presence cures our ills before they become fatal. The knowledge that we are never alone calms the troubled sea of our lives and speaks peace to our souls. KOH118-119
Thank You for Your calming peace, Lord, in the midst of what often are troubled seas. Go before me today, I pray. Amen. 
16:8 First of all, Messiah asserts without any equivocation that He has kept the Lord always before Him. Jehovah has been the One for whom He lived. He has never done anything in self-will; everything has been done in obedience to His Father’s will.
Because He is at my right hand, I shall not be moved. In Scripture the right hand speaks of:
Power (Ps. 89:13)
Safety (Ps. 20:6)
Honor (Ps. 45:9; 110:1)
Pleasure (Ps. 16:11)
Favor (Ps. 80:17)
Support (Ps. 18:35).
Here it speaks of safety and security.
