Just a thought on confession that we need to make sure we understand. Originally God set the standard with the Law. Now man cannot be holy before God since to follow this standard is impossible for man. So God provided a way to cleanse the people. Now NO sin can be before God and therefore He had to provide a way to cleanse the people. This was done through the sacrificial system that enabled man to shed his sin onto an animal who would be killed.
It sound brutal but make sense when you look at it through sin before God. Now comes Jesus who died once for our sins. The problem is 1 John 1:9 says:
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
Now back to the sacrificial system which needed to be done for each sin. It was something than many we constantly doing and needed to be done to remain just before God. Now back to the New Covenant with the people. We are taught that Jesus’ death is applied to ALL our sins; past, present and future. The problem is many believe it is one confession for ALL sin.
In reality this is false and keeps us separated from God. If we confess and then knowingly sin without confession we are without God. Because of this confession is a constant activity for me. It’s simplest to catch it, figuratively lay your hand on Jesus’ head and confess the sin.
Do it when necessary. I like to start all prayers with confession. Specific when I know or general with asking God to shed light on my sins when I don’t know. The key is it’s best to keep those paths open at all times.
