How does one lovingly stand up for the truth if the truth being stood upon is offensive to someone? Is it more loving to remain silent rather to instruct? Is it more noble to be passive or vocal? How will they learn if they are not taught?
A good teacher ought to strive to be gentle while not compromising. In the context of the hard things in scripture, Christians need grace and the power of the Holy Spirit in order to do this. We would be fooling ourselves if we think for one second we are able to do this without His help. With man this is impossible, but in Christ all things are possible. Lord, send me grace to finish this race unto my last breath and let Your will be done!
