It's not about holding a grudge. Retaining one's sins is about judgement because it is deserved. Peter brought godly judgement to Ananias and Sapphira. Even though they claimed to be Christians, their sins caught up with them. No one would say a judge in a courtroom convicts others out of unforgiveness or a grudge.
I guess we all happy when we hear of forgiveness but as soon as the bible mentions retaining sins, we twist that around to mean something other than the black and white of scripture. Jesus actually says if they retain someone's sin it is retained, yet you are trying to say that can not be. Am I correct in saying this or not?
Confess our sins to one another and be healed
About Ananias and Sapphira. You know they could have just told the truth that they sold the land for this much and said we are holding back part of it. It was theirs to sell and give or not give.
Now they were surprised as how did Peter know? Shocked and IMO they each had heart attacks and died.
This lying cheating, stealing, is going on this very day all over, people masquerading as believer's and are not.
This is why Christ will say go away to those that work iniquity, act as if they are for others when in truth only out for themselves. And is why it is a personal free choice for each individual to want to know God for one purpose
"Comfort God by letting God know that you would see God just to dwell in God's Presence. Not for teaching, not for material gain, not even for a message, but for God. The longing of the human heart to be loved for itself is something caught from the Great Divine Heart."
Motive is what all will be judged on, purpose and God knows, if purpose not right, God does not reveal truth to the ones that have malice, and continues to be kind, to lead one to change ones mind from unbelief to belief
Romans 2:4 Or do you show contempt for the riches of his
kindness, forbearance and patience, not realizing that God’s
kindness is
intended to lead you to repentance?
Unbelief in God through Christ is the only issue that God never died for. The reason, God will not take away free choice. So it is only each person that can actually make the choice whether to either believe or not, personally
