We are not commanded to preach, hear, fast, watch, or give continually. But we are commanded to pray continually, as though prayer were more needful than all the rest...We lack continually, and we are tempted continually, and we sin continually. Therefore, we need to pray to God continually, that God would supply our wants and forgive our sins, and prevent our temptations.
To pray continually is to lift up our hearts to God and to pray in our thoughts.... though we open not our lips.
God is readier to give, than we to ask. Therefore let us pray that our neglect of prayer may be forgiven
---Henry Smith "The benefit of contentation."
