Jesus taught His disciples a parable to demonstrate to them that they should always pray and not give up. George Mueller's formula for prayer stated, "It is not enough to begin to pray, nor to pray aright; nor is it enough to continue for a time to pray; but we must patiently, believing, continue in prayer until we obtain an answer." This talk explores the power of persevering prayer and encourages us not to give up.
