As Paul was writing to Titus, giving him instructions which would establish the church in Crete, he viewed the younger man as a close relative, part of his family. To be more accurate, he recognised that both he and Titus shared one Father, God himself. Titus had been born again by God through Paul's ministry and had become like a son to be nurtured in the faith. Now he was able to nurture others too.
They both came to know God through the same route: by submitting to Jesus Christ as Saviour and Lord. And so they both experienced His grace and peace being poured out on them. So although Paul was an apostle and preacher, he was happy that Titus shared exactly the same faith as him, was equally saved through Jesus Christ and equally loved by God the Father. Yes, Paul had things to teach Titus but his greater knowledge did not make him more loved by God.
It is the same today: all those who have trusted in Jesus Christ are equals in the same family, share the same faith and are held in love by the same Father. Although younger Christians need help to grow as disciples, that does not mean that their mentors are spiritually superior to them. One of the great principles of the church is that we 'are all one in Christ Jesus' (Galatians 3:28). Take away that principle and the church becomes a club with the oldest, like the Pharisees, assuming a more 'spiritual position'. When that happens the vitality of new believers gets suppressed, thinking that they are not equal. Of course, it is important to respect those who are more mature, and to follow their instruction and example; but never to think that they matter to God more than the newest believer.
