Jesus says if you just think it, you have sinned Matt 5:28.
Yes many instants of sinful thoughts. Perhaps a million thoughts of adultery before actual adultery. So do you agree that Adam and Eve ''sinned' before they ate the fruit?
Sin incorporates all of man's physical senses, which all connects to his brain. Lucifer sinned in his heart before he even attempted through his actions to ascend to the heights of God. I believe Adam, and Eve sinned before actually going through the motions of eating. The outward actions part is just the manifestations of abiding sin.
Eze 28:13 You were in Eden, the garden of God.15
Every precious stone was your covering, the ruby, topaz, and emerald,
the chrysolite, onyx, and jasper the sapphire, turquoise, and beryl;
your settings and mounts were made of gold. On the day you were created they were prepared.
Eze 28:14 I placed you there with an anointed guardian cherub;
you were on the holy mountain of God; you walked about amidst fiery stones.
Eze 28:15 You were blameless in your behavior from
the day you were created,
until sin was discovered in you.
Eph 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.
1Jn 2:16 For all that is in the world—
the desires of the flesh and the desires of the eyes and pride of life—is not from the Father but is from the world.
1Pe 4:2 so as to live for the rest of the time in the flesh no longer for human passions but for the will of God.
1Pe 4:3 For the time that is past suffices for doing what the Gentiles want to do,
living in sensuality, passions, drunkenness, orgies, drinking parties, and lawless idolatry.
Gal 5:19 Now the works of the flesh are evident:
sexual immorality, impurity, sensuality,
Gal 5:20
idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions,
Gal 5:21
envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things
will not inherit the kingdom of God.
