Charles H. Spurgeon on Psalms 119:107

Quicken me, O Lord. How doth God quicken us? By reviving our suffering graces, such as our hope, patience, and faith. Thus he puts life into us again, that we may go on cheerfully in our service, by infusion of new comforts. He revives the heart of his contrite ones, so the prophet saith (Isaiah 57:15). This is very necessary, for the Psalmist saith elsewhere, "Quicken us, and we will call upon thy name" (Psalms 80:18). Discomfort and discouragement weaken our hands in calling upon God. Until the Lord cheers us again we have no life in prayer. By two things especially doth God quicken us in affliction, by reviving our sense of his love, and by reviving our hope of glory.
