One of the hidden jewels of the Church is godly discipline. There has been a great lack of teaching and encouragement in modern evangelicalism towards the godly disciplines of: Fasting, waiting on God, early rising, head coverings, prevailing prayer, systematic Bible reading, Bible memorization, kneeling in prayer, and many other godly traditions in Church history.
Many have been taught that such things are legalistic and should be avoided if possible. Yet in the New Testament all these disciplines were taught and practiced by the early Apostles. Our Lord Himself taught and practiced fasting.
The early Apostles would wait on God in His presence ministering to Him.
Our Lord would rise early before all others to pray and seek His Father.
The Scriptures encourage women to cover their heads in prayer.
Some in the early Church had a ministry of intercession.
The Apostles gave themselves to the careful study of Scripture.
Memorizing Scripture has been a principle of the people of God through both covenants.
The Apostle James prayed on his knees till they were worn like a camel. There are countless other examples of those whose works followed their faith.
