The problem is this: The moment there is a possibility of choice there is a risk of making the wrong choice. A perfect God of love wants to love and be loved perfectly. Real love involves our choice to love God back -- or we can reject Him. God took that risk. I suppose He could have created a world where the objects of his love had no choice but to love him, like robots. But that is not love.
C.S. Lewis put it this way in his classic Christian book Mere Christianity:
My generation (the baby-boomers) have illustrated the risk of
choosing as much (or more) than previous generations. My generation took a freedom to choose and twisted it into barbarity of the licence of choice where the weakest and most vulnerable must pay for the choices of those with power over them. Large swaths of my generation threw off restraint and have scoffed at the Giver of freedom.
This has resulted in the deaths of millions upon tens of millions of children before they ever saw the light of day or took their first breath. Now freedom to choose will soon expand to killing suicidal people with disabilities, incurable conditions or "psychological pain", in my nation (Canada). Choosing to reject God is wreaking havoc of the social and legal fabric of America too, and other parts of western civilization. We chose evil rather than good.
In the same way as people go to Auschwitz and wonder how such evil is possible, future generations may look at the remnants of our abortion clinics and wonder the same thing.
Our choices will either save us or condemn us.
The good news is that we can change what we have chosen and choose God rather than ourselves. The beautiful paradox is that when we give God our broken selves, He gives us back ourselves healed and more complete, able to finally love and be loved more fully than we ever imagined possible, if we allow Him to.
And that brings us back to the point of Holy Week which we are observing now. Christ's Passion and death on the cross was the ultimate expression of perfect love to pay the penalty for our sins and choosing evil over good. It is a free gift for all you accept it and believe in his atoning sacrifice at the cross. Repentance is liberating! It frees us from choosing what was wrong and evil to choosing what is right and holy. Repentance and faith in Christ opens new horizons for an ecstasy of experiencing His perfect love and inklings of paradisial joy that awaits God's children.
