The first commandment demands the worship of the one true God alone. Believers therefore must take up their cross and follow the one true God alone, the Lord Jesus Christ. Listen as Pastor Paul van Engelenhoven preaches from Matthew 16:24 on what is idolatry, what is the power of idolatry, how can one be freed from idols, and how can one live without idolatry? Then Jesus told his disciples, ‘If anyone would come after me, let him deny himself and take up his cross and follow me.’”
