1. He is a jealous God
Eight times in the Bible, God calls Himself or someone refers to Him as a “jealous God”. Nowadays, with the sin-filled world we live in, the word “jealous” is almost always associated with the negative, selfish feeling. However, with God, the meaning is the opposite.
When applied to God, jealously is something that marks God’s love for mankind. He wants to make sure we are not lead astray by anything. Anything that distracts us from the purpose God has put us here, makes God jealous for us (Deuteronomy 4:24, 6:15, Joshua 24:19, Nahum 1:2). He is jealous in a way that says He wants someone to be with Him because it is the best for that person (this is the opposite way humans think). So, one sin that is condemned in this commandment is anything that takes us away from what God knows is best.
2. He visits the iniquity of humans, even future humans not yet born
Idols could do nothing to save humans from their sins (1 Corinthians 8:4). Nothing made by human hands could or can save humans (Ephesians 8-9). However, the Israelites, and people today, still want to believe that their own works will get them to heaven. They do not believe that God is the only One who can save them. So, this commandment also condemns those who think their own works can help save them.
3. He shows mercy to those who follow Him
Those who follow God are blessed in so many ways that Paul had to word it this way, “nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.” (Romans 8:39).
However, the best blessing any human can have, is the saving grace of Jesus Christ to wash away their sins. I don’t hesitate to say this but I know it will not be well liked, but those who are un-saved (and thus have not had this blessing) are sinning. The one that is not saved has sinned because he has not repented. It is a sad fact that many will try to ignore or disguise but, nevertheless, it is true. Unbelief is, in fact, a sin.
So, once one gathers together the key points of the second commandment, which talks against idols, they can see that he who rejects the love of God, His Son who He sent as the Savior and repentance of their evil deeds, has effectively broking the commandment.
In a nutshell, he who rejects God’s loving, saving, mercy and grace has broken the second commandment. It is interesting to note that a person who trusts an idol actually does deny all of that in one swift move!
