In this passage, Jacob is an old man and he made a difficult journey because of the famine. God knew the famine would be severe and He was not surprised. God knows everything. Not everything that happens to us is good, but everything is used for good for those who love God and are called according to His purpose. Jacob had to go to Egypt because he was out of food. It is not wrong to cry/weep. It is not okay to cry because of whining, tantrums, etc. Every year we live seems shorter and we need to make the most of our days. Just because life can be difficult, we are not to give up.
