Assimilation: We blend into our culture so much that no-one can tell that we are Christians! We do not take sin or the bible seriously. Young people having sex, living together and then getting married is the norm and there is no substantial difference between the ruthless, ambitious, workaholic Christian businessman and his non-Christian counterpart. Assimilation is easy, any wimp can do it.
Rejection: We withdraw from non-Christian society and culture with the excuse that we are seeking to be holy. We spend our time fellowship with Christians and Christian braai’s and neglect our non-Christian friends and colleagues. Church becomes a force field against an evil, “what is the world coming to” society. We constantly pray for Jesus to come and rescue us, while smiting the rest of humanity. Rejection too is easy.
God’s way of relating to society is more difficult. God commands us to engage with society (no rejection!), while being the distinctive people of God he has called us to be (no assimilation!). Or like Jesus prayed, we are to be in the world not of the world. Peter wrote, “live such good lives among the pagans that, though they accuse you of doing wrong, they may see your good deeds and glorify God on the day he visits us.”
Jeremiah too had this perspective in Jeremiah 29:1-14. He told God’s people in exile in a pagan society to build houses, to get married and take out car insurance. He told them to engage their society, without selling out.
We are all called to this: Engaging our society for Jesus, while being the distinctive people of God. This is why Peter called the Christians he was writing to “exiles/ aliens” (1 Peter 2:11). God has called you to a mission for Jesus. God wants you to connect with your society for Jesus.
