Are you as grieved as God is about the spiritual destination of the lost? According to Barna among twentysomethings, only 6% have beliefs that qualify them as evangelical Christians. This should drive us to our knees for the young generation.
To make it more personal, every person I know has an aching longing about the spiritual condition of someone they love. We have prayed and will continue to pray, but we come to grips with the story of George Mueller, who prayed for the salvation of someone for over 50 years, and the person only came to Christ after Mueller's death. But still, we call out to the Lord for them from a full and burdened heart.
We pray in faith for the salvation of those for whom we are burdened. Effective prayer for the lost impacts God, people, and the kingdom of darkness. We are praying to God, for the benefit of a person, and in opposition to everything that the power of darkness is doing to prevent the person's coming to salvation.
