Why did Rachel steal her father’s household "gods"? Was it because she believed that the household "gods" had powers and she thought her father could find out from these "gods" where she had gone with Jacob.

Amazing example of an encounter with God the Son when Jacob wrestles with the “man”. He wrestled with God to secure a blessing. Do we wrestle with God to secure a blessing or do we wrestle with God in defiance in order to get away from His authority?

Jacob's name is changed to Israel. When there is a change of name there is a change of character. When we become believers we take on His name. When we take on His name, we take on His character. That of course means we change our way of doing things, we change our character, we become a new creation, His creation.

2 Cor 5:17
Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!
