Hold your tongue!
1Pe 3:8 Finally, be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous:
1Pe 3:9 Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.
1Pe 3:10 For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:
Talking about improving the home is an exciting, important and easily answered from the Bible topic. There are tons of things that could be talked about but notice this one:
Refrain (hold) your tongue from evil. When we are discussing things in our marriage it is easy to let it turn ugly. We talk at the wrong time–we are tired, worried, preoccupied with other things. We do not pay attention to what our partner is saying. We begin to be critical and say things to hurt and offend.
If we really want to improve our marriage then we need to decide now not to say things that are wrong, hurtful, evil, belittling, and never ever should we use curse words or insults.
Keep the conversation respectful.
