Most of us would have been taught about the faith as children or as adults, depending on whether we were baptised as infants or as adults. However, regardless of when and how we were taught, we are reminded in today's reading to "Keep alive in yourselves what you were taught in the beginning: as long as what you were taught in the beginning is alive in you, you will live in the Son and in the Father; and what is promised to you by his own promise is eternal life."
As we go on in life, we may face various challenges, persecution, temptation, etc. However, we should make every effort to remain faithful to Christ and to God. As the reading also reminds us: "You are anointed with truth, not with a lie, and as it has taught you, so you must stay in him. Live in Christ, then, my children, so that if he appears, we may have full confidence, and not turn from him in shame at his coming." Have we been taking heed to these words and remain in Christ, come what may? It may not be an easy task, but let us persevere and trust in God, knowing that God will care for us and not abandon us.
