Matthew 4:1-4 Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. After fasting forty days and forty nights, he was hungry. The tempter came to him and said, “If you are the Son of God, tell these stones to become bread.” Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’”
Notice Satan first tried to get Jesus to question who He was, "If you are the Son of God". Since we are not unaware of his (Satan's) schemes, he will try to get you to question who you are. Expect: If you are a child of God, … Don't fall for it. There is no 'IF', once you accept Jesus as your Lord and Savior. Then he wanted Jesus to turn the stones into bread. Yes, Jesus was hungry, but notice what Jesus said. The first part: 'Man shall not live on bread alone', Jesus is not saying we don't need bread (food) to live, we do, but not just food. We are only partially living (real, true, God-kind of life) if we only eat food. The last part of what Jesus said informs us of what we need to fulfill our living needs and that is we live 'on every word that comes from the mouth of God.', this is primarily the Word of God. Are you lacking that which is needed to 'live'? I pray that you get enough daily nutritional meals plus that you take enough time in the Word (Bible) to hear what Father God is speaking to you so that you can truly live.
