Balancing goodness (love) and severity (truth)
Rom 11:22: "Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness …" (NKJV).
It is interesting to note the number of times the Bible describes God as exhibiting two attributes that are polar opposites of each other. In this verse, they are goodness and severity. God's love is expressed in His goodness, but it is not His only characteristic. He is also severe (righteous) with those who disobey. He balances these attributes perfectly as he relates to His children.
In the same way, we are called to imitate God in our relationships with our kids. We cannot be always be "good" because there will be times of rebellion and disobedience in their lives. We cannot always be "severe" because that creates resentment and fear. A balance between the two is our goal, and God will give you the wisdom to achieve that balance if you ask (James 1:5).
Ask God for the wisdom to balance goodness and severity in your relationships with your children.
