It starts first as a thought. Then an idea is conceived form the thought. Like being pregnant. Then over time, the idea becomes a plan. And when the plan is finally rolled out, the sin gives birth and runs its course. The devil starts winning. God will help you overcome temptation! Ask Him. He will provide the way out.
James 1:14-16, Galatians 5:19-21, 1 Corinthians 10:13
