Hold fast

I am reminding you, brothers and sisters,
of the Gospel I preached to you, which you indeed received and in which you also stand.
Through it you are also being saved,
if you hold fast to the word I preached to you,
unless you believed in vain.  1 Cor 15:1-2

Reflection:
I learnt that we need to hold fast to the Word so that we get saved not just hearing or reading just once.
