Christian living (Practice)
Is our Christian practice consistent with Jesus Christ? We are not sinners because we sin; we sin because we are sinners. God looks into my heart for our spiritual obedience rather than perfection. We will never be perfect as long as we live in our body. Like David's experiences, God meets us in our heart rather than our mind therefore we need to focus on the "heart of the matter". Every wrong act or practice begins with a "thought". Even though, our actions may "appear to be right" but we need to understand that Christians are always engaged in a spiritual warfare. Proverbs 4:23, it says "Above all else, guard your heart, for it affects everything you do." Spiritual maturity requires great care and a true knowledge of ourselves to distinguish a spiritual burden from irritation around us but at the same time, we cannot close our minds to everything that is happening around us. "Be very careful, then, how you live--not as unwise but as wise, making the most of every opportunity, because the days are evil." (Ephesians 5:15-16). We are to worship God from our hearts because we are the temple of the living God (2 Corinthians 6:16), that God will search us and try us, and know our thoughts.(Psalm 139:23).
Our Christian practice (life) starts in our hearts. Our thoughts are the product of our thinking and it is not our thinking that shapes our character, but the Holy Spirit that leads our thoughts and shapes our character. A person who have the Holy Spirit in the heart will understand God's standards of "sin" because a Christian will understand God's holiness. A person without having the Holy Spirit in the heart will not understand God's holiness therefore a person will define God's definition of sin in a human point of view (rather than spirit).
