Masonic/Occult Symbols at John Macarthur's Grace To You
The Sunburst and the Pyramid
Albert Pike once stated, "The Masonic religion should be, by all of us initiates of the high degrees, maintained in the purity of the Luciferian doctrine. . ."
"The late Albert Pike, a Luciferian and highly influential Mason, wrote that the power of his deity [Lucifer] is symbolized by the sun: 'The sun is the ancient symbol of the life-giving and generative power of the Deity.'"
"The sun has ever been at the center of false religion. The Ancient Mystery Religions venerated the sun, the solar disk, as deity...These pagan philosophies...indicate the importance of the sun as symbol of satanic deity." (Codex Magica, Ch. 22). 
"Now today, the Masons, as did the apostate Jewish elders and priests in the days of Ezekiel, continue to worship Satan the sun God, also called Lucifer or Baal, by other names." (Codex Magica, Ch. 22).
The word of God states that the idolatry of sun worship is a denial of God:
"If I beheld the sun when it shined, or the moon walking in brightness; and my heart hath been secretly enticed... this also was an iniquity to be punished by the judge; for I should have denied the God who is above. (Job 31:26-28)"
The following logos for John Macarthur's Grace To You depict a letter "A" which resembles a pyramid (a Masonic symbol) within a sunburst. 
The following are two more examples of corporate logos employing a pyramid within a sunburst:

Rick Warren's Saddleback Church and Chuck Swindoll's Stonebriar Community Church also incorporate the sunburst in their church logos.
The Alliance of Confessing Evangelicals is another pseudo-Christian org that employs the sunburst.  Several men mentioned on this website are on the Alliance Council: John Macarthur, Al Mohler, Mark Dever, John Piper, Steve Lawson, Ligon Duncan, CJ Mahaney... Recall that "images of the sunburst symbolize Satan."
The Index Finger Near the Eye
The following website names "twelve gestures of the freemasons, which are spread over the press."  The first jesture on the list states, "...the index [finger] near the eyes...are distinct masonic signs..."
John Macarthur's sermons are broadcast on TV.  And not unlike the beginning of any TV episode, each broadcast has a short introduction followed by the same theme that repeats with each episode.  Each theme contains the same frame (seen below) with a man's index finger near his eye.  This gesture which occurs in the introduction to the GTY videos and would be a symbol of the all-seeing eye.
