IV. We must offer up ourselves to God, and our best affections and services, in the flames of devotion, v. 41. When we are in affliction, 1. We must look up to God as a God in the heavens, infinitely above us, and who has an incontestable dominion over us; for the heavens do rule, and are therefore not to be quarrelled with, but submitted to. 2. We must pray to him, with a believing expectation to receive mercy from him; for that is implied in our lifting up our hands to him (a gesture commonly used in prayer and sometimes put for it, as Ps. cxli. 2, Let the lifting up of my hands be as the evening sacrifice); it signifies our requesting mercy from him and our readiness to receive that mercy. (3.) Our hearts must go along with our prayers. We must lift up our hearts with our hands, as we must pour out our souls with our words. It is the heart that God looks at in that and every other service; for what will a sacrifice without a heart avail? If inward impressions be not in some measure answerable to outward expressions, we do but mock God and deceive ourselves. Praying is lifting up the soul to God (Ps. xxv. 1) as to our Father in heaven; and the soul that hopes to be with God in heaven for ever will thus, by frequent acts of devotion, be still learning the way thither and pressing forward in that way.
