The most vital question to ask about all who claim to be in Christ is this: Have they a soul thirst for God? Do they long for this? Is there something about them that tells you that they are always waiting for His next manifestation of Himself? Is their life centered on Him? Can they say with Paul that they forget everything in the past? Do they press forward more and more that they might know Him and that the knowledge might increase, until eventually beyond death and the grave they may bask eternally in ‘the sunshine of His face?’ That I might know Him!
