Three ways to think about life, progressions, increasing maturity, the way to God. The path home. That is the problem of modern man. Our world talks of grace, but it is talk of compromise, excusing sin. Grace is about forgiving sin, in God's way.
Sin is our problem.
When Stephen in Acts 7 surveys the OT, he describes a people stiff-necked and uncircumcised in heart and spirit. When I am brutally honest, it is my problem. It is the problem of mankind, society, the church. I am selfish, self-centered, it is a human tendency. I want what I want when I want it.
