In Context

6 Seek you the LORD while he may be found, call you on him while he is near:

7 Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return to the LORD, and he will have mercy on him; and to our God, for he will abundantly pardon.

8 For my thoughts are not your thoughts, neither are your ways my ways, said the LORD.

9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.

10 For as the rain comes down, and the snow from heaven, and returns not thither, but waters the earth, and makes it bring forth and bud, that it may give seed to the sower, and bread to the eater:

11 So shall my word be that goes forth out of my mouth: it shall not return to me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
