For the time will come when people will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. (2 Timothy 4:3 NIV)
If we do not believe in something we will fall for anything.
Simple truths in life seem to have given way to personal opinion. Things that we might have taken as self evident may now be called into question. What we may personally see as sound doctrine others may see completely differently.
We must accept there are differences between us while still holding on to our personal value system. Learning how to hold tightly to what you believe while giving voice to others, here lies the foundation to dialogue.
