The enemy wants people to feel condemned, guilty and ashamed of their sins, because as long as they feel thusly, they will hide, and not talk about things (as you noticed) and as long as people do not talk and share it is much harder to get help. It’s a very subtle and clever tactic.
Thanks for having the courage to ask the question.
The scripture which you have mentioned is found in Exodus 20:5 – now h good news is that exodus is in the Old Testament pre-Jesus.
We as believers today are under the New Testament (some Bible translations actually say “Covenant” instead of “Testament” which s more accurate.
Today under the new Covenant through Jesus, you have this wonderful bit of scripture:
“For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.”
(Hebrews 8:12-13)
God no longer remembers our sins, they are all forgiven and under the blood of Jesus, the curse is removed and finished for all time, and it also includes the generational curses that you have mentioned.
Now into the second point: dealing with lust and porn. I actually preached a message on this roughly a month ago, but I will summarize it here:
It’s not about us, or our law keeping, it is all about Jesus. The moment we try to conquer sin using our own self-efforts or self-control then we have already lost. The key to be clean and stay clean is to simply continue to fill ourselves with Jesus.
You have already noted that it’s easy to accomplish victory when you are focused on Him, and so you have already found the secret. Hang onto that diamond of wisdom because it is a precious treasure that will keep you well in victory.
We are instructed in 1st Thessalonians 5:17 to “Pray without ceasing.”
This has confused some people because they don’t actually understand what “praying” is… “Praying” is actually communion and communication with God. Abiding and resting in Him, getting a bigger vision of Jesus; it doesn’t have to be loud, or use long words, and it doesn’t have to stand on a specific ceremony.
Now the outcome of this? The more we can fill ourselves with Jesus and get a bigger revelation of Him, our sins and desires for sin will fall away by themselves, naturally because our old nature dies… replaced by His divine nature.
This is a partial meaning of 2nd Corinthians 5:17:
“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.”
We are all as believers, new creations in Christ. Yes the enemy will try to revive our old nature, but that old nature isn’t even us anymore, and the more we can realize that we are now together with Christ, the more we win.
