What does the Bible say about grace in the life of a believer?

In Mark 4:28, we see an analogy that describes the growth of grace in a believer's life, elaborating on the progression from the initial 'blade' of grace, to the 'ear', and finally to the 'full corn in the ear'. This metaphor illustrates the stages of spiritual growth: initial awakening to spiritual truths, followed by deeper understanding and maturity in faith. The Lord uses various means, such as conviction of sin and the illumination of the Holy Spirit, to lead His people to a clearer knowledge of His grace and truth. As believers grow, they move from a foundational knowledge to a more comprehensive understanding of God’s character and redemptive work in Christ, as they experience spiritual transformation throughout their lives.
