Temptation always seems to be near, which is what God said to Cain:

Genesis 4:3. And in process of time it came to pass that Cain brought an offering to the LORD* from the fruit of the ground. 4. And Abel also brought from the firstlings of his flock and from its fat. And the LORD* turned to Abel and his offering, 5. but He did not turn to Cain and to his offering. And Cain was very, very angry and his countenance fell. 6. And the LORD* said to Cain, “Why are you so angry? And why has your countenance fallen? 7. Behold, if you do well, you will be accepted. And if you do not do well, sin sits waiting at the door, and its desire is to possess you, but you can rule over it.” (Num. 32:23)

Numbers 32:23. But if you will not do so, behold, you have sinned against the LORD*, and be sure your sin will find you out.
