Placed into their heart

John 13:2  During supper, when the devil had already put it into the heart of Judas Iscariot, Simon’s son, to betray him,

Acts 5:3     But Peter said, “Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back for yourself part of the proceeds of the land?

Ephesians 2:3     among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.

Luke 22:31     “Simon, Simon, behold, Satan demanded to have you, that he might sift you like wheat

James 1:13    Let no one say when he is tempted, “I am being tempted by God,” for God cannot be tempted with evil, and he himself tempts no one.  But each person is tempted when he is lured and enticed by his own desire.  Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death.  Do not be deceived, my beloved brothers.  Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shadow due to change.

Ezra 7:27    Blessed be the LORD, the God of our fathers, who put such a thing as this into the heart of the king, to beautify the house of the LORD that is in Jerusalem,

Nehemiah 2:12     Then I arose in the night, I and a few men with me. And I told no one what my God had put into my heart to do for Jerusalem.

2 Corinthians 8:16     But thanks be to God, who put into the heart of Titus

Revelation 17:17    for God has put it into their hearts to carry out his purpose by being of one mind and handing over their royal power to the beast, until the words of God are fulfilled.

Romans 1:19  For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.  Claiming to be wise, they became fools

Out of the abundance of the heart the mouth speaks.  Note the examples above. Satan temps and places intents in the heart of man.  Yet it also says that man lured away and enticed by his own desires.  Man acts on these temptations, desires, enticements and gives way to them in their life.  What is our hope against such things happening.  The word of God.  His word will bring light to the darkness associated with sin.  It will give knowledge and wisdom to understand things of this world that are contrary to God and as well things of God that are good for the heart, mind, and soul.  Our own sinful nature and it’s desires can not be left on their own for our nature is contrary to God and His ways.  Our help comes from God and through His word of hope, guidance, love, mercy, courage, promises, light, redemption, refuge, peace….  Staying in God’s word is the beginning of the battle for our soul.
