1 I waited for the Lord my God,
Messiah exhibited as our once-for-all Sacrifice, and all our Salvation
The use of this psalm in Hebrews 10:5 & 6, gives it an undeniably Messianic content. Though David is the suffering servant, he is also the singing king. This new song, which he composed, is one that celebrates the Messiah King. David’s experience is a shadow that is used to prophetically point to a greater suffering Servant. But notice that God put the new song in David’s mouth. The Spirit of Christ, the Word, imbues David with thoughts, and words equal to express those thoughts. This is not a product of his imagination, but of inspiration. That is the difference between psalmody and hymnody.
We are taught that suffering is the environment in which to practise waiting, and waiting patiently. The trial of our faith worketh patience. There is a sense of endurance in these words, but also of active waiting. It is not done in passivity, but a constant activity. There was no refraining or hiding from declaring and preaching righteousness by David or Christ. Suffering actually emboldened them.
