Satan’s story to Eve in Genesis 3 and to Jesus in Matthew 4 was that they could live independently of God, that is, they could be their own god, set their own standards, let circumstances dictate their decision. But it is a lie.
Either God controls your life by your choosing to let him, or Satan controls your life by your choosing to let him and by your choosing to just go with flow. You and I were designed by God to be ruled by a spirit . Our choice is not whether to be ruled, but rather by which spirit we will be ruled.
So, the Christian’s life is based on decisions, the process of making deliberate right choices without being swayed by Satan’s input into our appetites or emotions.
In Satan’s temptation of Eve in Genesis 3 and in his temptation of Jesus in Matthew 4, we see the tactics he used and still uses with us. While varied in their details, most temptations fall into one of three categories as listed in 1 John 2:16: the lust of the flesh, the lust of the eyes, and the pride of life.
