REFLECTION
The Christian journey calls believers to move from spiritual infancy into full maturity. To explore the theme “Becoming an Adult Child of God,” we must first define its core ideas. A “child of God” is someone born into God’s family through faith in Jesus Christ. “Becoming an adult,” however, speaks of growth, freedom, and spiritual maturity—moving past fear, external rule-keeping, and spiritual childhood into the full rights and responsibilities of an heir. In Galatians 3:27–4:7, the Apostle Paul shows that faith in Christ removes worldly divisions, ends the reign of the law as an elementary guardian, and grants believers the Spirit of adoption as mature sons and daughters. Paul wrote this letter to Christians in Galatia who, having believed in Christ, were being pressured to return to Jewish ceremonial law to earn God’s favour. Paul corrects them by demonstrating that returning to legalism is like an adult choosing to live like a child under a strict guardian.
Spiritual adulthood begins with a shared spiritual identity that transcends human divisions. Paul writes: “For all of you who were baptised into Christ have clothed yourselves with Christ. There is neither Jew nor Gentile, neither slave nor free, nor is there any male and female, for you are all one in Christ Jesus” (Galatians 3:27–28). A mature child of God no longer derives worth or standing from racial superiority, social status, or gender privilege. In practice, this means treating every fellow believer—regardless of tribe, wealth, or background—with equal dignity and Christian love. As Colossians 3:12 urges: “Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience.”
Second, maturity means stepping into spiritual freedom and heirship rather than living in legalistic slavery. Paul explains: “What I am saying is that as long as an heir is underage, he is no different from a slave, although he owns the whole estate. The heir is subject to guardians and trustees until the time set by his father” (Galatians 4:1–2). Under the Old Testament law, believers were like underage children who required rigid rules to restrain them. But when the set time arrived, God sent Jesus Christ “to redeem those under the law, that we might receive adoption to sonship” (Galatians 4:5). An adult child of God obeys out of gratitude, not legalistic dread. A practical example is giving or serving in church: an immature believer gives begrudgingly out of fear of divine punishment, whereas a mature believer gives generously out of joy, knowing that “each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver” (2 Corinthians 9:7).
Finally, an adult child of God possesses an intimate, Spirit-led relationship with the Father. Paul declares: “Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, ‘Abba, Father.’ So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir” (Galatians 4:6–7). Intimacy replaces religious distance. In daily life, this enables us to approach God boldly in times of distress rather than hiding in shame. As affirmed in Romans 8:15: “The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, ‘Abba, Father.’”
To become an adult child of God means laying aside external legalism, living in unity with others, and embracing the full inheritance of grace as an heir through the Holy Spirit. Stop living like a spiritual minor bound by fear and petty rules. Step forward in bold faith, take responsibility for your spiritual walk, and live openly as a cherished son or daughter of the Almighty Father.
Prayer
Heavenly Father, thank You for adopting me into Your family through Jesus Christ and clothing me in His righteousness. Deliver me from legalistic fear and spiritual immaturity. Teach me to walk daily in the liberty, love, and intimacy of Your Holy Spirit as Your true heir, crying out to You in wholehearted trust. In Jesus’ name, Amen.
