Spiritual growth is a fundamental principle of godly, Christian living. Once a person has rid themselves of sin, primarily through the sacrifice of Jesus Christ and secondarily through personal overcoming, they must replace sin with a life of righteousness. Without this growth, a spiritual vacuum forms, leading to regression and the return of sin with greater force. Our goal is to develop righteous, holy, spiritual character, mirroring the character of Jesus Christ, and growth in righteousness is the path to achieving this. The Days of Unleavened Bread serve as a yearly reminder of the dual principle of putting away sin and growing in righteousness. Both actions are equally essential; we must thoroughly rid ourselves of sin and channel our energy into growing in righteousness by internalizing God's law. This law, as a guide for righteous living, has both negative aspects, defining sin, and positive aspects, providing a standard to emulate. We are urged to focus on positive, growth-oriented activities—wholesome, helpful, service-oriented works, words, and deeds—that leave little room for sin, following the example of Jesus Christ who filled His life with good works. Under the New Covenant, God's laws are no longer distant on tables of stone but are etched into our minds and hearts by the Holy Spirit. This internalization allows us to make these laws our own, shaping our character to reflect God's. True knowledge of God comes from living His way of life, applying His laws, and walking in His shoes. This intimate familiarity with godly living provides insight into God Himself, strengthening faith and fostering spiritual growth over time. God provides ministers to equip and edify Christians, helping them reach spiritual maturity and attain the fullness of the character of Jesus Christ. This goal requires growth in all areas, striving to become just like Him. God expects prodigious growth from us, transforming the lowly into the wise, strong, noble, and glorious, following the footsteps of Jesus Christ who exemplified this journey. Growth in righteousness, akin to imitating Christ, is a cooperative effort with God. While we may not understand the intricate ways in which growth occurs, by studying, praying, meditating, fasting, serving, and applying what we know, we foster this development. God works behind the scenes, guiding and supporting us through the natural stages of growth—from novice to journeyman to veteran—ensuring that with our cooperation, growth is inevitable. This process, though often painful and requiring sacrifice, is supported by God's promise to supply what we need to bear fruit, bringing glory to Him as we grow in righteousness and put on the mind and character of our Lord Jesus Christ.
