- They were isolated.
- They lowered their guards.
- They made plans to spend time together.
Don't buy the lies that illicit sex and romance are selling. Instead, buy in -- hook, line, and sinker -- to the wisdom of Proverbs 4-9 (emphasis added):
Proverbs 4:20-23, 25-27
My son, be attentive to my words; incline your ear to my sayings. Let them not escape from your sight; keep them within your heart. For they are life to those who find them, and healing to all their flesh. Keep your heart with all vigilance, for from it flow the springs of life. ... Let your eyes look directly forward, and your gaze be straight before you. Ponder the path of your feet; then all your ways will be sure. Do not swerve to the right or to the left; turn your foot away from evil.Proverbs 6:32-33
He who commits adultery lacks sense; he who does it destroys himself. He will get wounds and dishonor, and his disgrace will not be wiped away.Proverbs 6:27-29
Can a man carry fire next to his chest and his clothes not be burned? Or can one walk on hot coals and his feet not be scorched? So is he who goes in to his neighbor's wife; none who touches her will go unpunished.Proverbs 7:21-23
With much seductive speech she persuades him; with her smooth talk she compels him. All at once (does it give you chills?) he follows her, as an ox goes to the slaughter, or as a stag is caught fast till an arrow pierces its liver; as a bird rushes into a snare; he does not know that it will cost him his life.
