Passing on knowledge with love
1 Cor 8:1: Knowledge puffs up, but love builds up (NIV).
Knowledge alone doesn't make you an effective parent—It is the ability to pass that knowledge along lovingly. A child who is afraid of the dark and thinks something is hiding under the bed probably won't be convinced by an argument against the existence of monsters! They are much more likely to feel safe when you sit beside them and walk through their fears with them.
Likewise, Bible knowledge can be a weapon if it is not handled with love and care. Too often, Bible verses are presented in a way that obscures the real intent of Jesus—to show us His love. Knowledge offered with love helps the weak believer become stronger.
Talk about the Bible with an attitude of love, and your kids are more likely to receive it gratefully.
