Willful disobedience will highlight our rebellion and evil will attack us. If we then return to that particular sin, we are intentionally disobeying God. However, the Bible does require confession and repentance when we understand our wrongs - a full turning away from them. You are not condemned if you have accepted Christ as your Savior (Romans 8:1).
Tool two: Humans are imperfect and everyone sins. We say we are Christian but we don't live like one. When we dismiss any of these biblical mandates, we invite the devil's attention because we lie.
What does a Christian life look like? Christians attend church regardless of the times, mandates or seasons (Hebrews 10:25) Christians put 10% of their income in the offering plate (Malachi 3:9-11) they abstain from sexual immorality in all of its forms (1 Corinthians 6:9) they love (John 13:34, 35) they forgive (Matthew 6:15) and they seek a relationship with Jesus, not just a religion about him (Matthew 6:33). Unfortunately, many people consider themselves Christian but do not take God seriously when choosing a lifestyle. So when the enemy comes to attack, he is looking for several qualifiers to see if we are ideal prey: Are we a practicing Christian or a hypocrite? Do we engage in repeated, sinful behaviors? Has our bloodline ever been cleansed in Christ? (This has to do with generational sin.) Do we love our neighbor? One: The devil has no right to torment a believer in Christ unless he has permission (Job 1:6-12).
