What is the will of the Father?

What is the will of the Father? How do we know the will of the Father? It greatly confuses me when I decide on something and someone questions it. Is that the will of the Lord? It is really upsetting for me, then again I understand that question is for me to reflect upon my decision. Sometimes I feel that after everything that has happened in my life, I am no longer capable of making right decisions. Sometimes, it also feels like people are quick to judge and look down on me because of it, as if saying, "Look what you've done to your life."  But then again I know that God writes straight our crooked lines. His words give me hope that it is still not too late for me to make it up for him and try to do his will. I want to be what he has planned me to be. I know real joy and happiness  are only possible with God. 

Reading 1, Isaiah 26:1-6

1 That day, this song will be sung in Judah: 'We have a fortress city, the walls and ramparts provide safety.

2 Open the gates! Let the upright nation come in, the nation that keeps faith!

3 This is the plan decreed: you will guarantee peace, the peace entrusted to you.

4 Trust in Yahweh for ever, for Yahweh is a rock for ever.

5 He has brought low the dwellers on the heights, the lofty citadel; he lays it low, brings it to the ground, flings it down in the dust.

6 It will be trodden under foot, by the feet of the needy, the steps of the weak.'

Responsorial Psalm, Psalms 118:1, 8-9, 19-21, 25-27

1 Alleluia! Give thanks to Yahweh for he is good, for his faithful love endures for ever.

8 It is better to take refuge in Yahweh than to rely on human beings;

9 better to take refuge in Yahweh than to rely on princes.

19 Open for me the gates of saving justice, I shall go in and thank Yahweh.

20 This is the gate of Yahweh, where the upright go in.

21 I thank you for hearing me, and making yourself my Saviour.

25 We beg you, Yahweh, save us, we beg you, Yahweh, give us victory!

26 Blessed in the name of Yahweh is he who is coming! We bless you from the house of Yahweh.

27 Yahweh is God, he gives us light. Link your processions, branches in hand, up to the horns of the altar.

Gospel, Matthew 7:21, 24-27

21 'It is not anyone who says to me, "Lord, Lord," who will enter the kingdom of Heaven, but the person who does the will of my Father in heaven.

24 'Therefore, everyone who listens to these words of mine and acts on them will be like a sensible man who built his house on rock.

25 Rain came down, floods rose, gales blew and hurled themselves against that house, and it did not fall: it was founded on rock.

26 But everyone who listens to these words of mine and does not act on them will be like a stupid man who built his house on sand.

27 Rain came down, floods rose, gales blew and struck that house, and it fell; and what a fall it had!'
