Read Genesis 27:18-29
One lie always leads to another lie. Jacob kept adding sins to his previous ones. First, he impersonated his brother. Second, he lied to his father when he said, "I am Esau."
Finally, he even went so far as to bring the name of the Lord into his deceit, for he said, "Because the LORD thy God brought it to me" (Gen. 27:20).
Jacob most probably did not anticipate all of his father's questions; therefore, he had to have quick answers, which caused him to get into deeper and deeper trouble with his lies.
Jacob must have thought the scheme had worked. No doubt Rebekah was carefully listening to what was going on and also thought the plan had worked! The flesh prides itself on its achievements. But there were to be many sad results from the works of the flesh.
A kiss was part of Jacob's deception of Isaac, even as a kiss was part of Judas's betrayal of Christ. Isaac was deceived, and he pronounced the blessing on Jacob, but it was a long time before the blessing was fulfilled in Jacob's life.
Because he had to reap what he had sown before he was ready to receive the benefits, 30 years passed before Jacob realized the benefits of the blessing.
How much we blame the Lord for things that are nothing but acts of the flesh--the reaping of what we have sown. How tragic it is when we blame the Lord for the works of the flesh.
"He that worketh deceit shall not dwell within my house: he that telleth lies shall not tarry in my sight" (Ps. 101:7).
