In the last few decades social researchers have discovered a truth contained in Scripture for millennia: beliefs lead to behaviors, behaviors create habits, and habits shape character. If we want right behaviors (orthopraxy) and upright character we need to start with right beliefs (orthodoxy)
Yet, nowhere is his regard for doctrine more ringing than when he says: “If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.”
Jesus stresses this connection in his final words when he commissions his disciples to “go and make disciples of all nations … teaching them to obey everything I have commanded you.”
In the parable of the sower, Jesus warns his hearers about rootless faith stemming from the failure to take hold of gospel truths. It’s a warning he repeats in his discourse on the end times, as he urges his disciples to watch and understand so they won’t be deceived.
