II John 4 "I rejoiced greatly that I found of thy children walking in truth, as we have received a commandment from the Father."
There is no greater joy for a parent than to see and know that their children are saved and living their lives for the Lord and according to His Word.
On the other hand...there is no greater sadness and burden on the heart of a parent who raised their child or children according to God's Word and see them go the way of the world. I know many parents who trained up their children by God's Word...and had them in church all their lives...prayed with them and for them...only to see them forsake those teachings and go their own way and not God's way.
I feel very blessed to be able to say that...to this point in their lives...my children are living for God and serving Him in our church. Not all parents can say this. I understand that there is always that chance that my children would turn and go their own way. Just the thought of that burdens my heart. It's always easy for them to go God's way when they live at home and they know they don't have a choice. Our children know that as long as they live at home that they will be expected to participate in the things of God and going to church. The true test will come when they get married and move into their own home. We can only pray that they take what they learned growing up and continue with it when they have a home of their own.
Fewer homes these days are living according to God's Word because the children are growing up and either move out on their own prematurely and choose to forsake what they were taught or they get married and don't live how they learned to live while at home with momma and daddy.
We as parents do have a promise from God if we train up our children as God would have us to. Proverbs 22:6 "Train up a child in the way he should go: and when he is old, he will not depart from it." What a blessing if a parent can say they can rejoice to find that their children walk in truth. And what a sadness there is for those who can't say that.
We as parents can only do all we know to do with the help of the Lord to train our children God's ways...but the ultimate decision will become theirs if they choose it as an adult or not.
