It is in a moment that the most solemn of all decisions is made—the soul's surrender to the Lord Jesus Christ. The soul itself, amid the conflict of emotions, may scarcely be able to tell the precise moment when the Yes is spoken; or it may have been back in early childhood and be forgotten.
There may have been long preparation going forward, and the soul may have been hesitating and trembling on the verge of surrender, but the Yes that means acceptance of Christ and brings salvation is spoken in a moment.
A moment may make the difference between life and death. 'Too late' may be too late by a moment only. The missing of the right moment may be the missing of the "accepted time."
