Sinclair Ferguson is probably my favorite living theologian. His latest book, one of the best I’ve read this year, is a significantly revised edition of his first book, published in the UK in 1980 as Add to Your Faith, and in the U.S. as Taking the Christian Life Seriously in the U.S. in 1981. The book would be appropriate for believers in any stage of their Christian walk.
The author tells us that the writers of the New Testament had a deep concern to see Christians grow to spiritual maturity. Mature Christians possess the qualities which only Jesus Christ can produce, because he alone has exhibited them perfectly. We must go on to maturity, because Jesus went on to maturity.
The author spends a lot of time in Hebrews, which he calls “the letter about maturity”. In that book, Jesus’ experience is seen as the foundation for our going on to maturity. In addition to the teaching of Hebrews, the author tells us that we should not be surprised that there are frequent references to the importance of spiritual maturity in Paul’s letters. The author tells us that If maturity was the great goal of the apostles’ ministry, then it ought to be a goal in our own lives too, and the deep desire of our hearts. He also looks at Psalm 119, which he refers to as “the psalm of maturity”, Psalm 131 and also Ephesians 6.
Subjects that the author touches on are hindrances to maturity, indwelling sin, spiritual discernment, the Father’s pruning, abiding in Christ and living in union with Him, God’s guidance, assurance of salvation, suffering, tests, trials and temptations, opposition and perseverance.
Throughout the book the author refers to many heroes of the faith such as John Bunyan, J.C. Ryle, Anselm, Augustine, Calvin, Luther, John Owen, Robert Murray M‘Cheyne, and many more.
The author tells us that there is no easy way to maturity, no shortcuts. The path to maturity is: Lay aside your own ambitions. Lay aside your own wisdom. Lay aside your own self-assurance. Make the Lord your ambition. Make the Lord himself your hope and your only wisdom.
I highlighted a number of passages in this excellent book. Here are 20 of my favorite quotes:
1. Ability to focus our gaze, fill our minds, and devote our hearts to Jesus Christ is a basic element in real Christian growth. Inability to do so is a sign of immaturity.
2. Secret failure cannot remain hidden. If we do not deal with our indwelling sin, it will eventually catch up with us.
3. Grace, not man-made rules and regulations, produces spiritual maturity.
4. Growing in spiritual discernment is an essential element in spiritual maturity.
5. The Father’s pruning includes his providences and interventions in our lives, which are designed to produce in us mature and well-rounded Christian character.
6. In a sense our Lord bore more fruit through his dying than through his teaching, and through going to the cross than through his coming to the manger.
7. Abiding in Christ, living in union with him, drawing all our spiritual resources from him, involves allowing his word to ‘abide’ in us, that is to fill our minds and affections and dominate our lives.
8. Feeding our minds with the word of Christ is essential if our hearts are to be filled with the joy of Christ.
9. Applying the precepts and principles of Scripture with the Spirit’s help leads to a life of obedience and ultimately to Christlikeness.
10. God has made it possible for his children to enjoy assurance. More than that, as a loving Father he wants us to be sure of his love for us.
11. Faith alone justifies, through Christ alone. It is Christ alone who saves through faith. Assurance is our enjoyment of that justification and salvation.
12. If God has given his Son for our salvation, we can be sure he will withhold nothing from us that is for our good.
13. For rather than destroy the purposes of God, afflictions in our lives form an important part of those purposes. Ultimately, they serve to build rather than demolish the believer’s assurance of salvation.
14. Assurance of salvation is assurance of Jesus. He becomes everything to us.
15. Knowing that the Lord will lead and guide us is one of the great stabilizing blessings of the Christian life.
16. Wanting God’s guidance means seeking his will and not my own.
17. God’s guidance in our lives today is related to his long-term ongoing work of transforming us. It is shaped to our growth in grace. His goal in the specific guidance we seek is secondary to the life-transformation he is determined to pursue.
18. The way God’s sovereign will unfolds for us is through our knowledge of, and submission to, his revealed will.
19. Sin is the internal enemy of spiritual growth.
20. For the more we see our sin the more wonderful the grace of Christ will seem to be.
