Our gospel came not unto you in word only, hut also in power, and in the Holy Ghost, and in much assurance. (1 Thessalonians 1:5)
One marked characteristic of modern evangelicalism is its lack of assurance, resulting in a pathetic search for external evidence to corroborate its faith. It sets out bravely to declare its trust in Christ, but is shortly overawed by the counter declarations of science and philosophy and before long it is looking about for some collateral evidence to restore its confidence.
The faith of the Christian must rest upon Christ Himself. He is the mystery of Godliness, a miracle, and emergence of the Deity into time and space for a reason and a purpose. He is complete in Himself, and gains nothing from any human philosophy.
The New Testament points to Christ and says God now commands all men everywhere to repent: because He has appointed a day in which He will judge the world in righteousness by that Man He has ordained! Our assurance is the fact that He raised Him from the dead. In that, God validated forever the claims of Christ. He is who He said He was and what He said He was. So, Christ is enough! To have Him and nothing else is to be rich beyond all conceiving.
