Overloaded by Risë Rafferty

Skeletal muscle has this amazing ability to adapt to being overloaded. When weight bearing loads are repeatedly placed upon them, muscle responds by increasing in size and strength. Exercise is the most powerful stimuli for inducing reorganization of muscle cells. Genetics play a large role in muscle mass potential, as does diet and growth factors. These growth factors have become common terms in body building circles. They are advertised as having the ability to supersize muscles.

Growth factors are produced by the body and are very involved in muscle building. They work with each other to help bring about the desired goal: well-defined, larger muscles. One of these growth factors is a substance called insulin-like growth factor 1 (IGF-1). IGF-1 stimulates growth. It has been found to promote bone growth in osteoporotic individuals, enhance the growth of children, and has been linked with preventing muscle wasting in the elderly.

Several tissues produce IGF-1. Muscles themselves produce it in response to resistance exercise. IGF-1 circulating in the blood is typically produced …

Saved "and" Called by Jeffrey Rosario

Saved “and” Called

June 27, 2016 | Jeffrey Rosario

As the apostle Paul sat waiting as a prisoner in Rome, he was conscious of the fact that his future was likely one of martyrdom. Instead of sitting idly, he wrote several letters, the last of which was the second letter to Timothy. Timothy was a young man that Paul cared for deeply. “When Timothy was little more than a boy, Paul took him with him as his companion in labor” (Manuscript, p. 117a, 1901). As Paul thought about his final moments, he desired to pass on to Timothy a legacy that he could aspire to. The letter is theologically rich and reveals some inspiring insights about Paul’s frame of mind as a follower of Jesus and a successful evangelist.

It seems as though Timothy lacked some boldness and confidence in his calling because Paul needed to reassure him that God “does not make us timid, but gives us power, love and self-discipline” (2 Timothy 1:7, NIV). To press this matter further, Paul gives Timothy the ultimate foundation on which …

Something to Say at Princeton University by Ty Gibson

Something to Say at Princeton University

June 3, 2016 | Ty Gibson

Ministry needs to happen everywhere—even among the educated elite. Evangelists recognize that the highly educated are the most difficult class to reach with the gospel, generally speaking. Recently, feeling the weight of this fact, I delivered six lectures at Princeton University.

Knowledge, like wealth, is a two-edged sword: the more I have, the less needy I may appear in my own eyes. “Education” itself is a tricky concept. Who is educated and who is not?

According to the apostle Paul, “If anyone thinks that he knows anything, he knows nothing yet as he ought to know. But if anyone loves God, this one is known by Him” (1 Corinthians 8:2-3). Theoretical knowledge can create the illusion that one knows more than one actually does. Of course, this is not an argument in favor of ignorance, but rather in favor of humility, and in favor of a different kind of knowing. Paul does not recommend stupidity, but he does recommend that our knowledge be grounded in God’s love.

The most educated …

Prostate Cancer—Caught in the Headlights by Risë Rafferty

Prostate Cancer—Caught in the Headlights

June 1, 2016 | Risë Rafferty, RDN

It’s nighttime. You are driving a country road when a deer leaps onto the pavement in front of you, stops in the middle of the road, seemingly looks straight at you and freezes. If the deer kept his eyes focused on the direction he was originally headed he would have had a good chance of bounding away to safety, but it’s as if looking into the headlights Tased him. Why does that happen?!

The eyes of the deer were designed to be able to see at night. Their pupils are elliptical and can dilate to cover the entire width of the eye to take in more light. Their lens is larger than ours, again giving it better night vision. In addition, they have a reflector behind the retina that reflects light within the eye. David C. Yancy, a deer biologist with the Kentucky Department of Fish and Wildlife Resource, explains that when a deer’s eyes are fully dilated to capture as much light as possible, the intense headlight beam of …
