Your age does not excuse you from obeying the divine commands. Abraham was sorely tested in his old age. The words of the Lord seemed terrible and uncalled-for to the stricken old man, yet he never questioned their justice or hesitated in his obedience. He might have pleaded that he was old and feeble, and could not sacrifice the son who was the joy of his life. He might have reminded the Lord that this command conflicted with the promises that had been given in regard to this son. But the obedience of Abraham was without a murmur or a reproach. His trust in God was implicit. 1TT 500.3
The faith of Abraham should be our example, yet how few will patiently endure a simple test of reproof for the sins which imperil their eternal welfare. How few receive reproof with humility, and profit by it. God's claim upon our faith, our services, our affections, should meet with a cheerful response. We are infinite debtors to the Lord and should unhesitatingly comply with the least of His requirements. In order to be a commandment breaker it is not necessary that we should trample upon the whole moral code. If one precept is disregarded, we are transgressors of the sacred law. But if we would be true commandment keepers we should strictly observe every requirement that God has enjoined upon us. 1TT 501.1
