Every parent is called by God to be a teacher who not only declares God's truths but also demonstrates them, so that a life of faith is imparted, not just information.
In the final verses of Ecclesiastes, the compiler of the Teacher's words reminds us that what we must take away from his work is not a sense of hopeless in the face of life's apparent pointlessness, but instead, a fear of God a desire to obey Him.
In spite of life's bitterness, the Teacher in Ecclesiastes call his readers to rejoice in life's sweetness. But in light of new life in Jesus, we can rejoice now, not in spite of reality, but in light of the reality of our redemption in Him.
Even though messages about Hell are often labelled 'offensive' or 'antiquated' or 'irrelevent', God's word is clear about the reality that those without the righteousness of Christ will eternally experience God's justice because of their condition of rebellion against God.
One day, God's justice will be poured out fully and finally. One that day, all will stand before the judgement seat of Christ, even those covered by His righteousness.
Because the perfect justice of God and the perfect grace of God met at the cross of Jesus Christ, we can be declared innocent before God; made right with God and reconciled to Him.
While the justice of God is often neglected as one of His attributes, if we have experienced grace through Jesus Christ, then God's sin-destroying justice should cause us to rejoice in who He is and what He will do for His glory.
