Being married or going into marriage for some people is nothing as they say but for some it's like a war and battle to them because they are thinking on how to change their partners.
Planning on changing your partner will only attract pain, sorrow and quarrel in your home.
Firstly, do you want to change your partner?
Start from yourself,when you begin to work on yourself and it becomes evidence to your spouse to see,your spouse will change.
He or she will want to follow your footstep.
You don't force your spouse to follow your vision, they need to see the impactation in you and they will move along with you.
This is what the bible call faith sense not the true faith.
That's the carnally minded spouse,to prove yourself and vision to them before they accept to move along with you.
The spiritually minded spouse move along with your vision without you ,proving it to them,they already believe in you
God bless you
