Acts 10:14-15 “Surely not, Lord!” Peter replied. “I have never eaten anything impure or unclean.” The voice spoke to him a second time, “Do not call anything impure that God has made clean.”
Peter fell into a trance and saw a vision and this served not only as a ammendment to abolish the ceremonial law to prohibit eating of certain meat, but is more deep then merely that.
When truly come to Christ in faith and repentence we are made clean, declared guiltless because of Christ Jesus. To still beat ourselves up over our falleness and sins is to “bring a charge against God’s elect”
And it says, “Who will bring any charge against those whom God has chosen? It is God who justifies. Who then is the one who condemns? No one. Christ Jesus who died—more than that, who was raised to life—is at the right hand of God and is also interceding for us.” (Romans 8:33-34)
If God won’t accuse us, or the devil cannot condemn us, then who do we think we are to call ourselves “sinful unclean wretches”?
Yes we may still have points that need growth and besetting sins and habits we are trying to overcome but our standing in God’s sight remains the same, “Not guilty! Payed for by the blood of Christ”
We should not slander and condemn what God has saved, not other believers, not ourselves.
