You may have seen or heard some variation of this saying: “If you want to go fast, go alone. But if you want to go far, go together.” It’s a lovely thought, isn’t it? But is there any solid research to reassure us that these words are not just lovely, but true?

Yes! In fact, one such study by British and American researchers demonstrated that people estimated the size of mountains as significantly smaller if they were standing with someone else as opposed to when standing alone. In other words, “social support” matters—so much so that it causes even the size of mountains to shrink in our minds.

David found that kind of encouragement to be both lovely and true in his friendship with Jonathan. The jealous anger of King Saul was like an insurmountable mountain in David’s story causing him to fear for his very life (see 1 Samuel 19:9-18). Without some sort of support—in this case his closest friend—the story could have been drastically different. But Jonathan, “grieved at his father’s shameful treatment of David” (20:34), stood by his friend. “Why should he be put to death?” he asked (v. 32). Their God-ordained friendship bolstered David, allowing him to become Israel’s king.

Our friendships matter. And when God is at the center of them, we can spur each other on to do greater things than we might imagine.
