Does Our Fruit Show That We Are Doing The Will Of Our Father In Heaven?

Today's Focus Scripture:  Matthew 7:11-21

Matthew 7:11-20
11 If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give what is good to those who ask Him!
12 “In everything, therefore, treat people the same way you want them to treat you, for this is the Law and the Prophets.
13 “Enter through the narrow gate; for the gate is wide and the way is broad that leads to destruction, and there are many who enter through it.
14 For the gate is small and the way is narrow that leads to life, and there are few who find it.
15 “Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.
16 You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they? 17 So every good tree bears good fruit, but the bad tree bears bad fruit.
18 A good tree cannot produce bad fruit, nor can a bad tree produce good fruit.
19 Every tree that does not bear good fruit is cut down and thrown into the fire.
20 So then, you will know them by their fruits.

A LITTLE LAGNIAPPE: 
How many "Believers" are in this boat?  What must it be like for the one who thinks they are doing the will of the Lord, to think they are serving Jesus, to think they are firm in their belief, their doctrines, and "religion," only to find out all they have done is practice lawlessness and to have Jesus inform them on their day of Judgement that He never knew them, and that they practiced lawlessness for all that time instead of actually serving Jesus?

A REAL EYE OPENER FOR SURE TO THOSE WHO FOOLED THEMSELVES THEIR ENTIRE WALK WITH JESUS.  Just Who did they think they were praying to and serving all that time?

Matthew 7:21-23 
21 “Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter.
22 Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’
23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness.’
