Sin is whatever is not of the truth, the complete truth.
Iniquity is the constant engagement or implementation of sins with the hope of obtaining a beneficial result.
Transgressions, well, are simply the failings of upholding any law.
So, what are you to do now when you sin? Are you to cry all day like David? Nope! Are you to run and hide like Adam and Eve? Nope! Are you to go on the run like Jacob? Nope! Are you to regret to the point of condemning yourself like Judas? Nope!
You can cry like Peter, seeing the hurt you have unintentionally caused. You can’t spend the rest of your life crying. So go and suffer with those you’ve hurt. And better yet, rejoice for the freedom you now have to not only stop going in the wrong direction but also suffer along with those you’ve hurt, the freedom that comes from knowing God through the cross of Christ. Without any fear whatsoever, but with the joy, the freedom, the power that grace is in us to live by Christ abundantly, rejoice in Christ as you suffer with those you’ve hurt.
Is there somewhere in the Bible where it says to kneel down and beg God for forgiveness? Nope!
What does the gospel say about your sins? They’ve been forgiven on account of Christ Jesus. So what’s left for you to do? Freely repent with joy and rest. If going in one direction have caused you to sin, how about you now try the opposite direction?
Was your sin fornication? Castration or physical torture won’t stop those thoughts from oppressing your mind. How about praying God to help you find a caring and faithful partner to get married, knowing all the weight that comes with marriage? Thinking that a sexual act will fix your problem is always a sin itself. But the conditions around such act that can make turn it into an iniquity. And the resulting false message that the sexual act had sent, trying to convey to the other that you care for her when all you really cared about was risking the health of that person with either a pregnancy of even some sexually transmissible diseases is a transgression of some basic moral laws.
Was your sin stealing? Dismemberment won’t keep you from envying that which you cannot afford. What about asking God to help you find a legitimate job, knowing the requirements that come with such a job? The stealing is a sin in itself. Yet, taking something that did not belong to you is not always a sin. But the conditions around such act can make it a sin. For instance, things properly disposed by their owners don’t belong to any one in particular anymore. But thinking that you’d be satisfied with taking something that rightfully belong to another without their available authorization, that’s your sin against yourself and the owner because no matter how many times you engage in such act, you will never be satisfied with doing what you hope others never get to do to you.
Was your sin lying? Removing your tongue won’t stop you from finding ways to deceive others. What about understanding that Christ is your freedom to tell the truth and not fear whatever retaliation you may be threatened with because God is your provider, your comfort through Christ always? Giving incomplete or inaccurate information is a sin itself, but the conditions around such act can make it your iniquity. Many unknowingly lie or misinform others. But thinking that keeping others in the dark by withholding the truth, the complete truth, would bring you satisfaction is a sin, and engaging in such acts leads to iniquity, being trained in the wrong direction, and transgressions of your own moral law which demands that others tell you the truth.
Whatever your sin, iniquity whatever that oppresses your mind, Jesus Christ is your way out.
“And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can endure it.” (1 Corinthians 10:13).
Jesus’s death on our behalf is our way out of the marital contract we had with sin. He is our way into eternal life, eternal joy, eternal peace, eternal rest, for He is risen and continually maintain his position as our high priest, sitting. Sitting because his sacrifice for our sins is once and for all time. Yes, we are not ashamed to say that we were in the wrong and that by the grace of God, we are now in the right, the righteousness of God, freely given through the blood, the burial and resurrection of Jesus Christ.
So what should you do today when you realized that you’ve sinned, that you’re in the wrong? With thanksgiving to God for his everlasting forgiveness at the cross, freely repent. Grace trains you into the righteousness of God, not into the fear of condemnation. Grace trains you into what is useful, beneficial, and revealing of your joy, your peace, your rest in Christ Jesus.
As King David once said in the Spirit as a foretelling of the gospel,
“Bless the Lord, O my soul, and all that is within me, bless his holy name! Bless the Lord, O my soul, and forget not all his benefits, who forgives all your iniquity, who heals all your diseases, who redeems your life from the pit, who crowns you with steadfast love and mercy, who satisfies you with good so that your youth is renewed like the eagle’s.” (Psalm 103:1-5)
