God said to Cain, “If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it” (Genesis 4:7).
You pray for God’s guidance for a job, a husband, or a new pair of shoes. Beware that an “open door” may not be God’s door but a door of opportunity to sin.
Temptation is the enticement to do evil, to disobey God. Every temptation comes down to a decision: Will I obey God or listen to the voice that offers what my sinful flesh wants?
As Christians, we’re promised that God leads us. If you’ve been born again, you should expect the Spirit of God to lead you (Romans 8:14). The problem is that your sinful flesh also leads you, warring against the Holy Spirit (Romans 7:23). It is only when you walk by the Spirit in submission to the Scriptures that you won’t fulfill the lustful desires of the flesh (Galatians 5:16).
Adam’s son Cain was warned by God that sin was waiting, crouching like a lion ready to pounce. Opportunity wasn’t necessarily God’s will.
One evening King David stood on his housetop and spied Bathsheba bathing. That “open door” was a temptation to sin that caused great suffering for David, Bathsheba, and the whole Jewish nation.
A fall often occurs when we’re faced with sin of presumption or defiance against what we know God has said. Be careful to examine every door by God’s Word – even when you feel peace about it. Feelings of peace are deceptive. Feelings, like doors, open and close, come and go, but God’s Word remains.
The law of the Lord is perfect, converting the soul; the testimony of the Lord is sure, making wise the simple … Keep back Your servant from presumptuous sins; let them not have dominion over me (Psalm 19:13).
