181 Then Jesus told his disciples a parable to show them that they should always pray and not give up.
9 God, whom I serve in my spirit in preaching the gospel of his Son, is my witness how constantly I remember you
(Read Romans 1:8-15)
We must show love for our friends, not only by praying for them, but by praising God for them. As in our purposes, so in our desires, we must remember to say, If the Lord will, James 4:15. Our journeys are made prosperous or otherwise, according to the will of God. We should readily impart to others what God has trusted to us, rejoicing to make others joyful, especially taking pleasure in communing with those who believe the same things with us. If redeemed by the blood, and converted by the grace of the Lord Jesus, we are altogether his; and for his sake we are debtors to all men, to do all the good we can. Such services are our duty.
Matthew Henry's Commentary on Luke 18:1
Commentary on Luke 18:1-8
(Read Luke 18:1-8)
All God's people are praying people. Here earnest steadiness in prayer for spiritual mercies is taught. The widow's earnestness prevailed even with the unjust judge: she might fear lest it should set him more against her; but our earnest prayer is pleasing to our God. Even to the end there will still be ground for the same complaint of weakness of faith.
