Guilt can come from all kinds of situations and sources. The bottom line is that guilt comes from violating authorites which a person allows to rule over their lives. Whatever the authorities might be, if an individual violates or goes against those authorities they will usually feel guilty afterwards.
The key word here is "allows". There are lots of authorities that people can be subject to but if they don't allow those authorities to rule their lives they will not feel guilty about violating them.
The guilt individuals feel depends upon how serious they are concerning certain authorities. Some people may pretend to feel guilty but are not actually that way since a particular authority they violated isn't that important to them.
With this thought in mind, people need to take a look at how important the authority of God's Word is in life. How serious do they take His word to heart? How much of it do they allow to rule and reign over their lives?
When an individual violates God's commandments and His Word, does he or she really feel guilty or is it not that important? Does such a person make excuses and try to justify their actions so they don't feel guilty?
Guilt is used by the Holy Spirit to keep people on track with God and living the Christian life. This guilt is called "conviction" and it becomes very much a part of a believer's lifestyle.
When we take God and His Word seriously then we should know that the Holy Spirit will convict us when we do things wrong and convince us to ask for forgiveness.
In this day and age it seems that God's Word is not taken serously and people tend to adapt only portions of the Bible to their lives. Whatever guilt is felt is rationalized away because God and His Word are not prominant and stable authorities for them.
Many people have devalued the Word of God and its authority over their lives. What value does God's Word have in your life? How serious do you take His Word and how much of His Word has authority over you?
Your guilt will determine the answer!
