Going to your favourite shop, you may see many things that you'd like to have. There's one snag though – they all have a price tag. Many people get themselves into deep debt because they don't 'count the cost' when they purchase something. Easy availability of credit cards has exacerbated the problem where people are in an economic mess because they failed to count the cost.
When Jesus said we must count the cost, he wasn’t talking about 'becoming' a Christian, but about 'being' a Christian.
Salvation is free – but there is a cost to discipleship.
