Hebrews 3:13 KJV
But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.
The responsibility that Christians have for one another is much more profound than most would accept in our generation. A telling sign of the weakness of modern Christianity is that we do not want to be held accountable and neither do we want the responsibility of holding others accountable. Christianity of this sort is too much bother. It interferes with the other priorities of life, a life in which our faith is but a part.
The sort of Christianity that the Bible describes would be labeled legalistic and invasive. It does make the Christian free to worship according to the dictates of his own conscience but it then compels the Christian to surrender that freedom to a community of like minded believers for the mutual benefit.
That community is a local New Testament Baptist Church.
