Strict walking is much despised in these days, but rest assured, dear reader, it is both the safest and the happiest. Worldly conformity, in any degree, is a snare to the soul, and makes it more and more liable to presumptuous sins. {Charles Spurgeon}
God commands us, "Do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God" {Romans 12:2}.
We, as believers, do walk a narrow path. This narrow path with borders is for our protection. All of God's commands are to protect us. We must teach our children this while they are young. We taught our children that the majority of rules we had for them came from God so when they left home, they would be accountable to God and not us.
The world has a strong pull. It wants you to compromise with it. It feels good and looks good but it isn't good. God's ways are good. They are the best path to travel on. I know. Life is much better when I am walking in obedience to God.
So stop being angry with your husband because he is always late, or isn't involved with the children enough, or eats too much, etc. Obey God. Love your husband. Love your in-laws. Love your children for love covers over a multitude of sin.
