"No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can endure it."
(First Epistle to the Corinthians, ch. 10, v. 13*)
The Greek word translated as "temptation" in the initial verse is peirasmos, but it also means "trial." Both meanings of the word are equivalent, but one or the other is chosen based on the context in a specific passage. As humans influenced by modern culture, music, literature, and cinema, we might naturally associate temptation with something we greatly desire to obtain, do, say, or think, but from which we refrain for various reasons. However, the ancient Greeks apparently saw things differently. Temptation is a type of testing of a person's essence, or simply put, you are being tempted/tested to see practically if you will be what you claimed to be.
We can see this in the Gospel of Matthew, ch. 4, where we are shown Jesus's test in the desert after His 40-day fast. The Scriptures say, "Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. And after fasting forty days and forty nights, he was hungry." (Matt. 4, v. 1-2, the bold text is ours) From the bold words, we see that the initiative for this test is from God the Father, with Satan merely being part of God's plan. The passage proceeds with three specific offers the enemy of our souls makes to Christ.
"Then the tempter approached Him and said, "If you are the Son of God, tell these stones to become bread." But he answered, "It is written: 'Man shall not live on bread alone, but on every word that comes from the mouth of God.'"
Then the devil took Him to the holy city of Jerusalem and set Him on the pinnacle of the temple, and said to Him, "If you are the Son of God, throw yourself down, for it is written: 'He will command his angels concerning you, and they will lift you up in their hands, so that you will not strike your foot against a stone.'" Jesus replied to him, "It is also written: 'Do not put the Lord your God to the test.'"
Finally, the devil took Him to a very high mountain and showed Him all the kingdoms of the world and their splendor, and said to Him, "All this I will give you if you will bow down and worship me." Then Jesus said to him, "Away from me, Satan! For it is written: 'Worship the Lord your God, and serve Him only.'" (Matt. 4, v. 3-10)
First, Jesus Christ is tested in His body - He becomes hungry after fasting 40 days in the desert, a place with extremely high temperatures during the day and cold at night. Our Savior's body is human, which means he also goes through the sensations and difficulties that we have in our human bodies. Christ also eats, sleeps, drinks water, and needs rest. The devil attacks His loyalty to the Father by addressing an obvious physical need—the need for food. However, Christ repels this temptation with a word from the Scriptures: "It is written: 'Man shall not live on bread alone, but on every word that comes from the mouth of God.'" In this, Jesus shows us that there is more than physical needs that gives us life, and that is God's word.
Conclusion: If you are tested or tempted in any physical area, remember this—beyond every human physical need stands God's word. It is "living, active," gives life strength, and compensates for every physical lack.
