Hebrews 11:15

Verse 15. And truly if they had been mindful of that country, etc, If they had remembered it with sufficient interest and affection to have made them desirous to return.

They might have had opportunity to have returned. The journey was not so long or perilous that they could not have retraced their steps, it would have been no more difficult or dangerous for them to do that than it was to make the journey at first. This shows that their remaining as strangers and sojourners in the land of Canaan was voluntary. They preferred it, with all its inconveniences and hardships, to return to their native land. The same thing is true of all the people of God now. If they choose to return to the world, and to engage again in all its vain pursuits, there is nothing to hinder them. There are "opportunities" enough. There are abundant inducements held out. There are numerous gay and worldly friends who would regard it as a matter of joy and triumph to have them return to vanity and folly again. They would welcome them to their society; rejoice to have them participate in their pleasures; and be willing that they should share in the honours and the wealth of the world. And they might do it. There are multitudes of Christians who could grace, as they once did, the ball-room; who could charm the social party by song and wit; who could rise to the highest posts of office, or compete successfully with others in the race for the acquisition of fame. They have seen and tasted enough of the vain pursuits of the world, to satisfy them with their vanity; they are convinced of the sinfulness of making these things the great objects of living; their affections are now fixed on higher and nobler objects, and they choose not to return to those pursuits again, but to live as strangers and sojourners on the earth--for there is nothing more voluntary than religion.

Verse 15 If they had been mindful of that country - They considered their right to the promises of God as dependent on their utter renunciation of Chaldea; and it was this that induced Abraham to cause his steward Eliezer to swear that he would not carry his son Isaac to Chaldea; see Gen 24:5-8. There idolatry reigned; and God had called them to be the patriarchs and progenitors of a people among whom the knowledge of the true God, and the worship required by him, should be established and preserved.
