Perhaps we have too low a view of what is happening when a man is blessed of God to preach and teach exactly what we need when we need it.
We cannot bring ourselves to Christ, nor would we have the desire to come to Him. And, even if our loved ones desired that we be raised to spiritual life, they do not have the power to bring us to Christ.
Even if all men had the desire to be saved (which we know that fallen, depraved man does not), he does not have the ability to move toward Christ. Salvation begins and ends in the will and power of God.
