The Apostle Paul told Timothy, a pastor in Ephesus, “What you have heard from me in the presence of many witnesses entrust to faithful men who will be able to teach others also” (2Tim 2:20). He also told Titus “Older women are to…teach what is good, and so train the young women to love their husbands and children…” (Titus 2:3). And he tells the whole congregation in Ephesus speaking the truth to one another in love, we are to grow up in every way into Him who is the head, that is, Christ” (Ephesians 4:15).
By God’s grace, He has designed the Christian life to be lived in community. We don’t have to live the Christian life alone – and we shouldn’t! We all need help from each other in understanding Scripture, applying it to our lives, staying faithful in prayer, and locking arms to fight against our own sins. One aspect of that community is one-to-one discipling friendships. A more experienced Christian might start a friendship with a younger believer for biblical and spiritual conversation and prayer. Or, a less experienced Christian might ask for that kind of input from an older brother or sister in Christ. You might also find it useful to meet with a Christian who is at about the same maturity level as you are to spur each other on to love, good deeds, and greater spiritual fruitfulness and maturity.
