Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Two elements are vital in preaching a sermon: the correct blending of the sermon and the actual act of preaching. Gospel sermons must be prepared to meet all the needs of humankind. We should explain our sermons so that the audience could understand. We should use strong verbs and short sentences.

To enjoy the fullness of God's blessings of protection, deliverance, and security, the people of God need to digest divine sermons. The sooner we understand that God is the one who has the final authority over all, the better off we will be. Avoid wasting a lot of energy worrying about things that are already under his control. God is still at work.

Mankind should seek every opportunity to be converted. The term "conversion" refers to the human response to the gospel. Conversion requires the commitment of the total personality, intellect, emotion, and will. This is how people respond to the message of the gospel when they understand the nature of Christ's atonement. They feel the guilt of conviction, love God, and surrender their wills to the offer of salvation.

Satan's forces of darkness are highly structured for the most destructive purposes. Therefore sermons with spiritual strength and courage are needed for our spiritual warfare. If you want to win the struggle against sin, depression, evil thoughts, immoral behavior, and demonic bondage, then submit to divine sermons. If we are not listening to divine sermons, we will drift off God's pathway and be controlled by the old nature and its appetites.

The Abdus Salam Memorial Meeting was held from the 19th to the 22nd of November, 1997 on the first anniversary of the death of Prof Abdus Salam, Nobel laureate and Founder-Director of the International Centre for Theoretical Physics. It was an opportunity for many of his colleagues and students to pay homage to him.

This invaluable volume, comprising the papers presented at the meeting, reflects the long-lasting passion of Prof Salam for the theory of the fundamental forces. Most of the contributions are concerned with recent developments in the theory of superstrings, including duality, D-branes and related topics.
