In the last blog, we saw that all sins create a wall between God and us, and we breech that spiritual Berlin Wall whenever we go to God, and seek His forgiveness. Here, we will look at some of the “big sins” we perhaps practiced in the past
Galatians 5:19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality,
20 idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions,
21 envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God
But before we go there, it is important that we see that while we may consider them “biggies:, God does not consider them unforgivable. To understand that, we need to look at some Greek grammar because English grammar is inadequate. It is not a participle-based language. Kione Greek is a participle-loving language, and the construction of the time element is crucial to understanding what Scripture says. The tense of the participle is somewhat irrelevant because the mood rules. In this case, it is active.
This phrase is very important: “that those who do such things will not inherit the kingdom of God.”
This does not state anything about “those who did these acts”, instead, it refers to ongoing action; thus using the verb “do” is an excellent translation because God does not hold our once-forgiven sins against us.
…Now the works of the flesh are evident: sexual immorality, impurity, sensuality…
The names of the acts of sexual immorality and other works of the flesh are important, not because they are “naughty words or “dirty words”, but because they all involve doing things with other people, sometimes becoming one flesh with them, and all the others with whom they practiced perversions. Practicing perversions with others with others is repulsive not because God forbids it, but it profanes the image of God in all humans. God created all humanity in that way, so practicing those things is akin to poking your finger in the eye of God.
Another important word in this section is the Greek word φαρμακεία transliterated as “pharmakaia”. The definition from a lectionary is
the use of magic, often involving drugs and the casting of spells upon people—‘to practice magic, to cast spells upon, to engage in sorcery, magic, sorcery.’
… ‘with your magic spells you deceived all the peoples (of the world)’ Re 18:23 
From the transliteration, you may have recognized the root word from which we get our English word “pharmacy”. Therefore, it is not an illogical leap to include those who introduce mood-changing chemicals into their bodies several times daily. Those chemicals ranges from caffeine to tobacco, marijuana, heroin, LSD, ecstasy, magic mushrooms or cocaine, meth, oxycodone, Adderall, Ritalin, and Vicodin frequently profane the image of God in which all humans are uniquely created.
That is why drug abuse of any sort is wrong; it causes us to be dependent on chemicals, but not God. Because the God of the Bible is a relational God, He wants humans to be dependent upon Himself alone, and not some strange chemical concoction.
The Greek word for that is πορνεία, transliterated as “pornea”. It is the root of the English word, “pornography” a compound word, meaning a writing about illicit sex with another person. Therefore, it is also a sin against the ones in the pornography, and the ones viewing porn.
Here is the lexical definition; it is far worse than the short definition above:
to engage in sexual immorality of any kind, often with the implication of prostitution—‘to engage in illicit sex, to commit fornication, sexual immorality, fornication, prostitution.’
‘the person who commits immorality sins against his own body’ 1 Cor 6:18 .
Of course, I am not attempting to lessen the seriousness of any sort of sexual immorality, but it is inconceivable that the same God Who created such pleasure in the act of marriage and the drive to reproduce would make this a second unpardonable sin. However, this sin is not without serious repercussions from a future spouse, and a lessening of the trust between the husband and wife, often leading to separation, disharmony, and sometimes divorce.
While our Enemy may wish to make your past sexual immorality into a Great Pyramid of Egypt sized obstacle to our relationship to God and our spouse, David makes a fantastic contrast between living with unconfessed sin, and living with forgiven sin:
Psalm 32: 2 Blessed is the man against whom the Lord counts no iniquity, and in whose spirit there is no deceit.
3 For when I kept silent, my bones wasted away through my groaning all day long.
4 For day and night your hand was heavy upon me; my strength was dried up as by the heat of summer
Please do not forget that David was both a murderer, and a sexually immoral person. Since God forgave him, so also can God forgive you. Do not listen to the condemning whispers from Satan that come into your ears, but surely know that even that is forgivable.
You see, EVERY sin is a “biggie” because God sent Jesus to take the death penalty for our sexual secrets, and all our other sins. Because Jesus died and rose that is our guarantee of total forgiveness, having a proper relationship with God the Father.
Knowing that should give us great joy because God wants us to have a great relationship. All you need to do is ask Him to forgive you, and He will do it; lasting forever.
