Salvation is available for all members of the human race. Salvation is the most important undertaking in all of God's universe. The salvation of sinners is never on the basis of God's merely passing over or closing His eyes to sin. God saves sinners on a completely righteous basis consistent with the divine holiness of His character. This is called grace. It relies on God so man cannot work for salvation, neither can he deserve it. We need to realise that the creation of this vast unmeasured universe was far less an undertaking than the working out of God's plan to save sinners.
However the acceptance of God's salvation by the sinner is the most simple thing in all of life. One need not be rich, nor wise, nor educated. Age is no barrier nor the colour of one's skin. The reception of the enormous benefits of God's redemption is based upon the simplest of terms so that there is no one in all this wide universe who need be turned away.
