Interpretation of a verse in the Bible: "To him that hath shall be given, and from him that hath not shall be taken away even that he hath.” (Matthew 13:12, 25:29, Mark 4: 25, and Luke 8:18 and 19:26)

On Wednesday, June 13, 1906, while at luncheon, my wife [Florence] asked 'Abdu'l-Baha concerning the interpretation of the following verse of the Gospel: "To him that hath shall be given, and from him that hath not shall be taken away even that he hath.” [Matthew 13:12, 25:29, Mark 4: 25, and Luke 8:18 and 19:26]

In answer 'Abdu'l-Baha said in part:

"This is the exposition of one of the great questions of Divine Wisdom which Christ has couched in this brief and simple utterance. The great question is this: In the world of existence, pause (or discontinuation of progress) marks the beginning of fall and decadence. For instance, as long as the bird soars or moves upward in the air, it is in progress. But no sooner it pauses than it begins to descend. Or, as long as a merchant lives on the interest or income produced by his capital his business is successful and in progress. But no sooner he begins to consume his capital then the beginning of his decadence is reached and he inclines toward bankruptcy. Hence it is customary amongst men of trade and business to say of one who draws on his capital for self-sustenance, 'It is all over with him.' Now by the word of Christ, ‘To him that hath shall be given,' is meant briefly: To him that hath the capital of Truth and Faith shall be given an increase of such when he employs this capital by living up to the requirements of Faith, and by communicating them to others in word and deed. Thus he who is endowed with any degree of capacity and ability must constantly exert himself in order to increase them, or he will see the beginning of failure and decadence. For this pause is like unto consuming ones capital, or allowing his capacity to decrease and thus fulfilling in himself the verdict, 'And from him that hath not shall be taken away even that he hath.'"

The meaning of ‘God created heaven and earth in six days'

The verse ‘God created heaven and earth in six days' has reference to the Day of God and the spiritual creation, for there was no day or night before the creation of this heaven and earth.

‘Abdu’l-Baha responds to a question: Does the Baha’i Faith accept the Bible?

[While aboard the ship to America, an American asked whether the Bahá'í Faith accepted the Bible. `Abdu'l-Bahá replied:]

This Cause acknowledges the truth of all the Books and all the Manifestations of God. The heavenly teachings are composed of two kinds of commandments. One kind is concerned with spiritual verities, with the perfections and virtues of the world of humanity. These commandments never change or alter. Each of the Books and the Prophets was the promulgator of these principles upon which all the religions are based, hence the foundation of all the divine religions is one. The second category of commandments is concerned with material principles and social issues. These are altered according to the exigencies of the age. For example, at the time of Christ the social laws of the Torah were changed.

Comparing Teachings of Jesus and Baha’u’llah

While in London, a friend asked ‘Abdu’l-Baha how the teachings of Bahá'u'lláh contrasted with the teachings of Jesus Christ. ‘Abdu’l-Baha responded:

"The teachings are the same. It is the same foundation and the same temple. Truth is one, and without division. The teachings of Jesus are in a concentrated form. Men do not agree to this day as to the meaning of many of His sayings. His teachings are as a flower in the bud. Today, the bud is unfolding into a flower! Bahá'u'lláh has expanded and fulfilled the teachings, and has applied them in detail to the whole world."
