Husbands, likewise, dwell with them with understanding, giving honor to the wife, as to the weaker vessel, and as being heirs together of the grace of life, that your prayers may not be hindered. (1 Peter 3:7 NKJV)
Sometimes, we forget that sin hinders prayers. We simply love to live our lives anyhow we like and presume that it is okay. However, it is not okay to walk outside the laws and precepts of Christ.
There is a new law and a new covenant sealed with the precious blood of Christ. That law is the law of the covenant that we have been commanded to obey.
When husbands refuse to treat their wives with honor and understanding as the weaker vessel, that very act of reduced love and weak understanding will hinder their prayers. So says the word of God.
On a general note, we need to live our lives in love and understanding towards one another so that our prayers will not be hindered.
May great grace be upon us in Jesus name.
