A recent survey asked respondents to identify the age at which they believed they became adults. Those who considered themselves adults pointed to specific behaviors as evidence of their status. Having a budget and buying a house topped the list as being marks of “adulting.” Other adult activities ranged from cooking dinner every weeknight and scheduling one’s own medical appointments, to the more humorous ability to choose to eat snacks for dinner or being excited to stay at home on a Saturday evening instead of going out.
The Bible says we should press on toward spiritual maturity as well. Paul wrote to the church at Ephesus, urging the people to “become mature, attaining to the whole measure of the fullness of Christ” (Ephesians 4:13). While we’re “young” in our faith, we’re vulnerable to “every wind of teaching” (v. 14), which often results in division among us. Instead, as we mature in our understanding of the truth, we function as a unified body under “him who is the head, that is, Christ” (v. 15).
God gave us His Spirit to help us grow into a full understanding of who He is (John 14:26), and He equips pastors and teachers to instruct and lead us toward maturity in our faith (Ephesians 4:11–12). Just as certain characteristics are evidence of physical maturity, our unity as His body is evidence of our spiritual growth.
