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). Salvation is free through Grace (undeserve kindness) of God and His unconditional love. Is God's grace cheap? Becoming a disciple, following Jesus Christ requires personal cost, giving up your selfish "me" and become like Christ. Love is NOT conditional however discipleship is conditional. Jesus might have grieved over His Cost of Discipleship requirements, but He never ran after them to try to win them with rosy promises. Christians all around us are trying every shortcut they can think of, to get "something for nothing" in the kingdom of God. Although God's grace has been given freely to humans who do not deserve it, the grace of God and point out that Jesus commanded us to take up our cross and follow Him. Our minds are so much set on things earthly and so little on things above. To grow in Christ as God desires demands on our submission to Him.
The point for Christ died for our sins according to the scriptures is great news. Jesus purged our sins, He mediates grace to all who believe, is wonderful news for this sinful nature world. Our Messiah, Jesus Christ, who gave Himself as a ransom for all Christians who did not reject the conviction of the Holy Spirit. God's will is for our redemption, adoption and the obtaining of our eternal inheritance in the heavenly blessings (Ephesians 3:10,11). God's gifts are many; His best gift is one which is the gift of Himself. Above all gifts, God desires most to give Himself to His people so that we can have eternal life instead of eternal death.
God's New Covenant is eternal because Christ is the mediator of the covenant, that we receive the promised eternal inheritance. That Covenant is that He has died as a ransom to set us free from the sins committed under the first Covenant. The Book of Hebrews explains that Jesus is the mediator, the executor, of The New Covenant (The New Testament). The word mediator comes from the verb "to mediate" which means a mediator is one who stands between two parties or two factions needing to be reconciled eternally. With that promise, as a Christian, I always thank God continually for our New Testament guarantees of spiritual life and freedom in Christ. The bond of the Covenant between God and US is ETERNAL that will never fail because it is God who has promised, and I have strong FAITH in His Character of His Eternal Promise.
Christ through His death and resurrection, every legal hindrance has been met and satisfied. There is nothing that can keep me from assurance except my own faith. Its not about thinking our way into salvation or to reason our way into salvation. The only way to get in is to believe Him with my heart which is sealed by the Holy Spirit. Because of Christ, we are Christians.
