Conversion is primarily a process, a transformation of a Christian's nature from human and carnal to godly and spiritual. Much of this transformation occurs in the mind, putting off selfish, sinful beliefs, inclinations, and approaches, and putting on their holy and righteous counterparts. However, conversion must also manifest in changed behavior, the fruit of God's Spirit accomplishing its miraculous work within us. Despite becoming Christians, some fail to progress in spiritual transformation, retaining pre-conversion natures evident in carnal behavior, acting like those who have not received God's grace. Conversion is the process of exercising mental and spiritual faculties of reason, understanding, and judgment. If we are not making judgments about events in our surroundings, determining right from wrong, and endeavoring to correct what is wrong, then we are failing in our conversion and risk neglecting our salvation. To advance in this spiritual transformation, diligence, earnestness, zeal, and deep commitment with eagerness are essential. Christians are advised to dedicate their lives to this process and stick with it to the end, as this is what those who will inherit the promises do. Christianity is not a path for the lazy; it requires striving to add to faith qualities such as virtue, knowledge, self-control, perseverance, godliness, brotherly kindness, and love. If these attributes are instilled into our characters, we will produce the kind of fruit God desires to see in us. Spiritual growth and producing fruit make our calling sure. Our maturity as Christians depends on zealously and diligently working to move our conversion forward. Real conversion is the transformation of our characters, intellects, emotions, actions, words, and very thoughts, from the evil way inspired by satan and man's carnal nature into the divine nature, the very nature of God Himself. Though challenges with carnality exist, working to overcome them and growing in grace allows us to progress, becoming complete and living in peace, with the assurance that the God of love and peace will be with us.

Conversion is not a one-time event but a lifelong process that begins with a single transformative moment. A person is initially converted upon repenting, accepting Jesus Christ as personal Savior, being baptized, and receiving the Holy Spirit through the laying on of hands. This initial step marks the beginning of a journey where one must continue to keep God's commandments, overcome sins, and bear the fruits of God's Spirit. However, many fail to persist in this transformation, falling back into old, sinful ways or reverting to carnality due to a lack of ongoing commitment to becoming more completely converted. The process of conversion mirrors the stages of salvation, involving past, present, and future aspects. God converts individuals upon the receipt of the Holy Spirit, yet the remainder of life is dedicated to living according to God's instructions and imitating the holy, righteous character of Jesus Christ. True and complete conversion to God's way of life will not be fully realized until the change to spirit in the resurrection from the dead. Those recently baptized and having received God's Spirit are like newborns in this lifelong transformation, needing to grow from carnal immaturity to Christ-like maturity. Conversion is described as spiritual development, akin to human growth from childhood to adulthood. As babies mature through various stages of life, Christians are to develop spiritually, moving from being unskilled in righteousness to attaining the full measure of the stature of Christ. The goal is to grow up in all things into Him who is the head, Christ, through a process of spiritual transformation of character. This ongoing conversion ensures readiness to fulfill the destiny and office God has prepared, a process that aligns with the natural growth of living organisms from a state of carnality to spirituality.

Sin plays a central role in the conversion process, as there would be no need for conversion without its destructive effects on humanity. Conversion involves turning from sin and the anti-God world it has spawned to follow God's way of life. God describes this process concisely, urging repentance and turning from transgressions to avoid ruin, casting away sins, and acquiring a new heart and spirit. Conversion is not an instantaneous event but a gradual process of turning toward righteousness and holiness over time. If a converted person sins, they do not automatically become unconverted, as it takes time and habitual sin to revert to an unconverted state. The battle against sin is ongoing, and walking in the light as He is in the light ensures fellowship with one another and cleansing from sin through the blood of Jesus Christ His Son. Confession of sins brings forgiveness and cleansing from all unrighteousness, as He is faithful and just. Even with the goal of living sinlessly, sinful human nature persists, and sins occur due to a deceitful and wicked heart. When sins are committed, admitting them, repenting, and seeking forgiveness allows Christ's blood to cover them, enabling continued striving against sin. Each step of overcoming sin and learning lessons contributes to character growth, transforming one into the image of Christ bit by bit. Conversion is not a solitary endeavor but a cooperative effort with God, who works through His Spirit to transform individuals into what He has purposed. This spiritual, creative process is God's workmanship, guiding individuals through every stage. The process remains incomplete in this life, as perfection cannot be fully achieved due to inherent human self-centeredness. Even with God's Spirit, occasional sins occur, but a converted person constantly works toward perfection under His guiding hand.
