Charles Spurgeon on Knowing Christ

“Grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ.”  —2 Peter 3:18
“Grow in grace”—not in one grace only, but in all grace. Grow in that root-grace, faith. Believe the promises more firmly than you have done. Let faith increase in fullness, constancy, simplicity. Grow also in love. Ask that your love may become extended, more intense, more practical, influencing every thought, word, and deed. Grow likewise in humility. Seek to lie very low, and know more of your own nothingness. As you grow downward in humility, seek also to grow upward—having nearer approaches to God in prayer and more intimate fellowship with Jesus. May God the Holy Spirit enable you to “grow in the knowledge of our Lord and Saviour.” He who grows not in the knowledge of Jesus, refuses to be blessed. To know Him is “life eternal,” and to advance in the knowledge of Him is to increase in happiness.
He who does not long to know more of Christ, knows nothing of Him yet. Whoever hath sipped this wine will thirst for more, for although Christ doth satisfy, yet it is such a satisfaction, that the appetite is not cloyed, but whetted. If you know the love of Jesus—as the hart panteth for the water-brooks, so will you pant after deeper draughts of His love. If you do not desire to know Him better, then you love Him not, for love always cries, “Nearer, nearer.”
Absence from Christ is hell; but the presence of Jesus is heaven. Rest not then content without an increasing acquaintance with Jesus. Seek to know more of Him in His divine nature, in His human relationship, in His finished work, in His death, in His resurrection, in His present glorious intercession, and in His future royal advent. Abide hard by the Cross, and search the mystery of His wounds. An increase of love to Jesus, and a more perfect apprehension of His love to us is one of the best tests of growth in grace.

“I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord.” —Philippians 3:8
Spiritual knowledge of Christ will be a personal knowledge. I cannot know Jesus through another person’s acquaintance with Him. No, I must know Him myself; I must know Him on my own account. It will be an intelligent knowledge—I must know Him, not as the visionary dreams of Him, but as the Word reveals Him. I must know His natures, divine and human. I must know His offices—His attributes—His works—His shame—His glory. I must meditate upon Him until I “comprehend with all saints what is the breadth, and length, and depth, and height; and know the love of Christ, which passeth knowledge.”
It will be an affectionate knowledge of Him; indeed, if I know Him at all, I must love Him. An ounce of heart knowledge is worth a ton of head learning. Our knowledge of Him will be a satisfying knowledge. When I know my Saviour, my mind will be full to the brim—I shall feel that I have that which my spirit panted after. “This is that bread whereof if a man eat he shall never hunger.” At the same time, it will be an exciting knowledge; the more I know of my Beloved, the more I shall want to know. The higher I climb the loftier will be the summits which invite my eager footsteps. I shall want the more as I get the more. Like the miser’s treasure, my gold will make me covet more.
To conclude; this knowledge of Christ Jesus will be a most happy one; in fact, so elevating, that sometimes it will completely bear me up above all trials, and doubts, and sorrows; and it will, while I enjoy it, make me something more than “Man that is born of woman, who is of few days, and full of trouble”; for it will fling about me the immortality of the everliving Saviour, and gird me with the golden girdle of His eternal joy. Come, my soul, sit at Jesus’ feet and learn of Him all this day.
