I agree, but the way you worded it does not reflect the above. You said God commanded you. Is 'love' a command for you?
loving them also means teaching them in the ways of the Lord
But as a Reformed you also believe that they will or will not be believers if God so predestined them to be, regardless of what you do, right?
So, whether you teach them or not, the outcome is already decided. What's the point of teaching them?
YES! And so it is with you. When Jesus gave us the two highest commandments, what did He say? :) All of the love we have to give comes from God. When it's easy, that love just comes sort of "naturally", without having to think about it. Other love is more difficult, like when we have to do what we do not want to do, and it is because of love. Sometimes love DOES take an effort.

Yes, I cannot affect their eternal destiny. That is solely within God's providence. That outcome is already decided, but part of MY outcome includes my teaching them. The point of teaching them is that God told me to. Because of God's grace and the faith He gave me, I want to please Him and obey. God is using me, along with others, to bring my children to a knowledge of God. They will hear God's word through people and reading the scriptures, just as I did. This is simply the way God has ordered things.
