(Jacob said): "You know that I have served your father with all my strength, yet your father has cheated me..."
The words written by Sir Walter Scott in his poem Marmion are very, very true: "O what a tangled web we weave, when first we practise to deceive".
The story in the book of Genesis involving Jacob shows a whole web of deceitfulness, cheating and being cheated. You can read the story if you have time in Genesis chapters 27 and onward. Jacob became a practised cheat and he found himself cheated. How true the New Testament words are: "Let no one deceive you with empty words, for because of these things the wrath of God comes upon the children of disobedience" (Ephesians 5:6).
You see, God is the God of truth, he hates lies, he hates cheating, whether it has to do with sexual wrongdoing, family relationships, or religious worship, God hates the sins of cheating and deceitfulness. One result of cheating is that a person has to go on covering up (or trying to cover up) the results of the first time they cheated. It usually gets worse and worse. It becomes like a soiled dirty rag. Telling the truth is always clean, even when it is not always easy. You can be sure God is on your side when you tell the truth and act truthfully and that is a bonus every time. "Lying lips are an abomination to the Lord." (Proverbs 12:22)
Make me to act truthfully at all times, O Lord.
