Mali ya Mungu
From your post,i guess you married recently and the challanges you are going is just misunderstandings .Learning is a process and at this time all you need is proper communication in the house.Be real,let her understand you,your likes & dislikes.In short,you need to talk & address this nagging issues.Rebuke her in love.At some point you might need to compromise for her sake & she should do the same to you if she is wise enough.No one is perfect and so you need to accommodate her to extent .
therez no short cut,if you are a husband,you MUST love your wife and she MUST submit to your authority.Its also Important that you pray to God to bring understanding between the two of you.The sad thing about it is that you have nicknamed her the devil.Men,that is wrong.There is power in a spoken word and so that would only worsen the situation.Can you give her new names like....darling.sweetheart,My dear......etc.Am sure you were using them before you started staying together,now what has changed apart from getting used to one another?
Wish you luck?
Without Holiness no man shall see God.Dear God,mould me to be a vessel of honour at this End times,to remain Obedient to your Word in all situations.Amen!
