Isaiah 55:6-7 (KJV) Seek ye the LORD while he may be found, call ye upon him while he is near:
Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.

This is written by myself

If we have sin on our heart we need to repent and come back to God because there is a time coming when it will be to late, thats when probation closes and then it will be to late for anyone to repent.
We also need to keep our thought on Jesus and to not lust after things of this world to keep our minds pure.
Revelation 22:11 (KJV) He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
