You may tell me that you have to spend time with your family. Really? They are more important than Christ? Didn't you say that you wanted your kids to follow Christ? If you are not setting an example, if you are not intimate with Him, where are they supposed to get the desire to follow Him? TV? Video Games? Their friends at school? What the heck are you going to talk to them about spiritually if you are not fresh in the Word?
If you do not know how, we can remedy that; start here. But stop telling yourself and others you do not have time for the one who created you for a purpose and gave you children to rear in the knowledge of Him. That is simply a lie.
