One observation I've picked up from raising three young boys is that nothing is a more tempting target of destruction than a standing tower of blocks! The five-year-old spends 10 minutes painstakingly stacks the wooden cubes in a precarious tower, and the three-year-old gleefully swats the tower down. The irritated older child tells the younger demolisher to go build his own tower, but the three-year-old isn't able to build his own tower.
Sometimes this comes to my mind when I'm fending off the probes of my atheist or agnostic friends (yes, I have friends who don't track with my spiritual beliefs). They seem eager to swat at the spiritual construct the Bible builds and (good-naturedly) attack the principles and revelations God gives in his Word, but are often unable to satisfactorily answer the same questions with their own worldview and I'm reminded that just because you can knock someone else's tower down doesn't mean you can build your own tower that can stand.
Christian apologist and philosopher Ravi Zacharias frames four universal questions that relate to origins, purpose, morality, and destiny that every individual in the world should attempt to align with their spiritual framework. If your current framework can't bring satisfaction to these questions, maybe you could give God his chance to answer them.
Where did I come from?
This foundational question is key to being able to answer the remaining three; in an anti-God or non-deity structure, there are no certain answers at all. Theories abound, but each idea conflicts with other theories and ideas. The Bible states that we are created in God's own image as beings that are designed to glorify and worship him. Almost every other theory of our origins makes us into an irredeemable cosmic accident.
Why am I here?
Many people have searched for the purpose of life, but the purpose the result of a cosmic accident can hardly stretch further than to satisfy bodily impulses; if humans are an extension of the animal kingdom, it wouldn't be rational to think that we have the capacities of anything spiritual or eternal; no soul, spirit, or conscience and little ability to make any lasting difference or hold any special value. The Westminster Shorter Catechism captures the essence of the Bible's message for our purpose when it states that our chief end is to "glorify God and enjoy Him forever." You have been placed here to walk with God, a gift that has been made available through Jesus Christ's death on the cross and resurrection from the dead. Everyone who calls out to God in recognition and faith of Jesus' death as the payment for their own sins can be saved and reconciled to God.
What is right and wrong?
The question of morality is one of the most difficult for non-deity structures to agree on, because it seems evident there are many issues of right and wrong that are transcendent - they are universally recognized as always wrong or always right. Kidnapping, murder, sex trafficking, cannibalism, etc. are examples of issues that we know must be universally wrong, regardless of culture or time period - we are responsible moral agents. If we are accidental beings, there would be no more morality attached to our behaviors than the animal kingdom. God's desire for us, however, goes beyond just being well-behaved; He desires us to become holy under his guidance and care.
Where am I going after this life?
This is a question many must come to grips with: God reveals that we can receive his inheritance of eternal life in heaven through the forgiveness that faith in Jesus' sacrifice on the cross brings to those who call to him in repentance. The Bible also reveals that there is a place of judgment for those who will reject God's gift in unbelief. If there is no God, and we somehow came into an unintentional existence, then there would be no reason to give the hear-after any second thought, but I believe God convicts us of the reality of eternity.
You can do your own research and ask your own questions by going to www.Bible.org or www.GotQuestions.org; it's never wrong to ask questions in your faith; it's never helpful to gloss over issues that you are struggling with. Don't be afraid to build the tower of faith God would love to see in your life!
