We will not hide Them from their children, shewing to the generation to come the praises of the LORD, and His strength, and His wonderful works that He hath done. For He established a Testimony in Jacob, and appointed a Law in Israel, which He commanded our fathers, that they should make Them known to their children: That the generation to come might know Them, even the children which should be born; who should arise and declare Them to their children: That they might set their hope in GOD, and not forget the works of GOD, but keep His Commandments: (Psalms 78:4-7)
While every person is responsible for their own relationship with Jesus Christ, and we cannot save anyone ourselves, GOD holds first and foremost fathers responsible for the education and upbringing of our children. We can be like the example of the Israelites who raised up generations that forgot GOD or we can be obedient to the instructions of GOD and with GOD's help raise up Godly offspring to do and accomplish the work of GOD in His Church. The testimony of a Godly family doing the will and work of GOD for His Glory is a blessing indeed.
And it's never too late to start, study first yourself and then share it with those that will listen, that they too might learn. GOD blesses our obedience in His time, and while there are consequences for our past disobedience, He can and will do His work in and through us.
And if you don't know the Lord; GOD, who is not willing that any should perish wants you to be born again. Repent, that is, turn from your sIn, and surrender to Him on His terms, and believe His Word and He will give you a brand new life of discipleship and fellowship with Him that is abundant and everlasting. Jesus loves you and desires to establish a covenant relationship with you that is real and personal. Trust Him and His Salvation and forgiveness today.
