Christ is all and in all. – Colossians 3:11

Not that we are sufficient of ourselves to think of anything as being from ourselves, but our sufficiency is from God. – 2 Corinthians 3:5

Whatever trials you have, my dear brother, Christ is all in all to meet them. Are you poor? He will make you rich in your poverty by His consoling presence. Are you sick? He will make your bed in your sickness and will so make your sick-bed better than the walks of health. Are you persecuted? Be it for His sake, and you may even leap for joy. Are you oppressed? Remember how He also was oppressed and afflicted; and you will have fellowship with Him in His sufferings. Amidst all the vicissitudes of this present life, Christ is all that the believer wants to bear him up and bear him through. No wave can sink the man who clings to this lifebuoy; he shall swim to glory on it.

I am a sinner, but my heart rests on its Savior; I am burdened with this body of sin and death but behold my Savior is formed in me the hope of glory. I am by nature an heir of wrath, even as others, but I am born into the second Adam’s household, and therefore I am beloved of the Most High, and a joint-heir with Christ. Is there Christ in thy heart beloved? Then everything that is there that would make thee sorrow may also suggest to thee a topic for joy. The saint is grieved to think that he has sin to confess, but he is glad to think that he is enabled to confess sin. The saint is vexed that he should have so much infirmity, yet he glories in infirmity because the power of Christ doth rest upon him. He is grieved day by day to observe his wanderings, but he is also rejoiced to see how the Good Shepherd follows him and restores his soul. So that all the evils and short comings in me which make me weep, also make me glad when Jesus is seen within. For all I see within myself lacking or sinful, I see a sufficient remedy in Christ who is all in all. ~ C.H. Spurgeon
