There will be times in spiritual warfare when you are under attack and may not know how to pray or be caught off guard.  My suggestion is that you keep a marker in your Bible at the Psalms 91 section and to read it aloud.
I start everyday reading this out loud over me and my family.
I've changed the scriptures to have a personal application.  To apply it to you and your loved ones change the I to "We".

Psalm 91 As A Personal Prayer

1 He who dwells in the secret place of the Most High

Shall abide under the shadow of the Almighty.

2 I will say of the LORD, “He is my refuge and my fortress;

My God, in Him I will trust.”

3 Surely He shall deliver me from the snare of the fowler

And from the perilous pestilence.

4 He shall cover me with His feathers,

And under His wings I shall take refuge;

His truth shall be my shield and buckler.

5 I shall not be afraid of the terror by night,

Nor of the arrow that flies by day,

6 Nor of the pestilence that walks in darkness,

Nor of the destruction that lays waste at noonday.

7 A thousand may fall at my side,

And ten thousand at my right hand;

But it shall not come near me.

8 Only with my eyes shall I look,

And see the reward of the wicked.

9 Because I have made the LORD, who is my refuge,

Even the Most High, my dwelling place,

10 No evil shall befall me,

Nor shall any plague come near my dwelling;

11 For He shall give His angels charge over me,

To keep me in all my ways.

12 In their hands they shall bear me up,

Lest I dash my foot against a stone.

13 I shall tread upon the lion and the cobra,

The young lion and the serpent I shall trample underfoot.

14 “Because I have set my love upon Him, therefore He will deliver me;

He will set me on high, because I have known His name.

15 I shall call upon Him, and He will answer me;

He will be with me in trouble;

He will deliver me and honor me.

16 With long life He will satisfy me,

And show me His salvation.”

In Jesus Name, Amen!
