When I was younger I would listen my mom make promises I think I knew as a child she could not keep. I knew she loved me and I knew she meant well when she said she would get me the bike I knew she could not afford. You see my mother did not raise me. She was not a well woman and was not able to take care of me but she wanted me to love her so she would often tell me she would do certain things I knew she was unable to do just because she wanted me to love her. Do you understand that? I don't think she knew how much it hurt me when I did not get that bike or that camera or the huge doll she wanted so desperately to give me.
I learned something from that. I learned never to make a promise I cannot keep. I never did it with my husband or my kids. Even now if I tell someone I am going to be somewhere at a certain time, I am there or I have a good reason for not being there like an illness or such. If say I am going to call someone at noon, I call them. I am a firm believer in keeping my word. Before making a promise, ask yourself if you can keep it. If you can't don't make it.
Proverbs 20:7 tells us that a righteous woman walks in her integrity.
