Of course, when a Christian says it is "impossible" to meet God's expectations, it is made possible by the change of heart and nature brought about by accepting Jesus Christ as one's Savior and receiving God's infinite gift of the indwelling Holy Spirit. "Marvel not that I said unto thee," Jesus told Nicodemus, "ye must be born again." (John 3:7). However, spiritual birth is only a beginning: growth must follow.
In both the Old and New Testaments, however, many of the recommendations, requests, and requirements that God asks of a believer have their difficulty in the presence of this word, "ALL."
This is only a tiny, partial reflection upon the role of this word in the Scriptures and in our Christian life.
That is not all, folks.
