God standard for what is evil should be the same standard for what is evil to man on earth. Our joy is that we make it in life without failing to standard in life. Our life is a road map for others.
The easiest way to succeed in anything is to be someone who dwell much by principles, standards, dos and don'ts rules.
The Lord God placed the man in the Garden of Eden to tend and watch over it. But the Lord God warned him, “You may freely eat the fruit of every tree in the garden-except the tree of the knowledge of good and evil. If you eat its fruit, you are sure to die.” (see. Genesis 2:15-17).
If really you want to fulfill destiny you shouldn't allow just anything into your life. Every dream will require you not to do certain things. Do you know those defining requirements? Let whoever comes your way know what those things are. And you must keep to it.
Set standards and principles for your life. Don't look or be cheap.
