It is my opinion that a person that is considering marriage (if they have children or not) should wait for GOD to give you the spouse HE has chosen for you. I do believe that the mate-to-be should have a loving relationship with the children if this is a second marriage.
Having a good relationship all together makes a happy family and love is present. The spouse and children should be in accordance with the word of GOD.
Husband is head of household,
Wife is to give honor to husband.
Children are to obey their patrents.
