so many focus on sin and not obeying and following GOD.
if you truly follow God then there is no room in your life, in your mind or heart for sin and sinful lust.
Sin is anything that causes you to disobey God. People sin by NOT doing good things just as much as doing the wrong things. People commit sins every day even if they do not recognize it but we have been take from under the Law of sin and death that we can not meet to the Law of the Spirit of mercy and grace that pardons us if we follow GOD and do good works for the glory of His name and keep our hearts and minds pure with His guidance.
If people are sinless upon acceptance of the Holy Spirit, if it is instanteous then what need is there for a mediator?
God does not tell us we are sinless but blameless for Jesus bears our sins and inquities in our place.
However God did not tell us to focus on our sins and how unworthy and sinful we are but tells us that Jesus died for the remission of ALL sins and to follow Him and His Holy Spirit.
Romans 8:33-39
King James Version (KJV)
33Who shall lay any thing to the charge of God's elect? It is God that justifieth.
34Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
35Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
36As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter.
37Nay, in all these things we are more than conquerors through him that loved us.
38For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
are you more than angels, principalities, powers, or any creature that you are able to separate yourself from the love of God?
If you are NOT lead by the Holy Spirit then you are not a child of God and just deceive yourself. therefore the focus is not on your sin but following God and Seeking His kingdom and will. If you are actively doing this then there is no room in your mind heart or life for sin.
