Will believers ever fully understand the complexity of salvation?
No. Salvation is profound and complex, yet simple enough for a child to enter. As believers grow in faith, they begin to realize how complex it is, but they will never plumb the depths of it. Its full complexity remains beyond complete human understanding.
Les explains that salvation is so profound and so complex, yet it is also so simple. It is simple when we first enter in, and a child can understand it. But as we grow in our faith as believers, we begin to realize how complex it all is. Les states that we will never plumb the depths of it. This follows his discussion of Abraham, who responded to God's call by faith.
