Let none imagine that without earnest effort on their part they can obtain the assurance of God's love. When the mind has been long permitted to dwell only on earthly things, it is a difficult matter to change the habits of thought. That which the eye sees and the ear hears too often attracts the attention and absorbs the interest. MYP 113.3
But if we would enter the city of God, and look upon Jesus in His glory, we must become accustomed to beholding Him with the eye of faith here. The words and the character of Christ should be often the subject of our thoughts and of our conversation; and each day some time should be especially devoted to prayerful meditation upon these sacred themes. MYP 114.1
