"That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us." Hebrews 6:18
It is utterly impossible for God to lie. The earth may be dissolved, and all creation reduced to chaos before God could lie. He would cease to be God if the faintest breath of a change, or the shadow of a turn should pass over the glorious Godhead. But it is impossible for God to lie. Therefore this holds out strong consolation for those that have fled for refuge to lay hold of the hope set before them.
And what is the ground of this strong consolation? This is the ground, that God has eternally determined and sworn by himself--that he will save and bless those that have "fled for refuge to the hope set before them in the gospel." This is the foundation of their consolation, this is the ground of their hope, that God has made such and such promises, and confirmed such and such promises by his solemn oath--that those who flee for refuge, and lay hold upon this hope, have a saving interest in and title to them, and have a manifest assurance of being "heirs of promise."
Now, did you ever in your life feel spiritual consolation? If ever you did, it was by laying hold of the hope set before you in the gospel. There was no consolation ever got by looking at fallen SELF. If ever there was any true consolation, any hope raised up in the heart, any solid comfort, it came out of the actings of living faith, embracing the blood and righteousness of Christ, tasting a measure of his preciousness, seeing his glory and beauty, and feeling the heart in some measure dissolved into nothingness at his footstool. Not looking at ourselves, but receiving as empty-sinners out of his fullness; not trusting to ourselves, or our own attainments, but going to Jesus, and receiving something into our hearts out of him. Nothing but this can give us consolation; and the more this is felt, the more this will give us "strong consolation."
