Non Desistas. Non Exieris. Never Give Up. Never Surrender. 

“Never give in. Never give in. Never, never, never, never—in nothing, great or small, large or petty—never give in, except to convictions of honour and good sense. Never yield to force. Never yield to the apparently overwhelming might of the enemy.” 
- Winston Churchill, Never Give In! The Best of Winston Churchill's Speeches
TRUST NO ONE.
For where God built a church, there the Devil would also build a chapel.  - Martin Luther
Psalm 23:4 NIV
Even though I walk through the darkest valley,
I will fear no evil, for You are with me;
Your rod and Your staff, they comfort me.
 Psalm 32:7 NIV
You are my hiding place;
You will protect me from trouble
and surround me with songs of deliverance.
Psalm 121:5-8 NIV, slightly revised
Lord, You watch over me—
You are the shade at my right hand;
the sun will not harm me by day,
nor the moon by night.
You will keep me from all harm—
You will watch over my life;
You will watch over my coming and going
both now and forevermore.
Romans 8:31, 37-39 NIV
If God is for us, who can be against us? … . We are more than conquerors through him who
loved us. For I am convinced that neither death nor life, neither angels nor demons, neither the
present nor the future, nor any powers, neither height nor depth, nor anything else in all
creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
Apostles' Creed 
I believe in God the Father almighty, Maker of heaven and earth,
and in Jesus Christ, His only Son, our Lord,
who was conceived of the Holy Spirit and born of the Virgin Mary,
who suffered under Pontius Pilate, was crucified, died, and was buried,
descended into hell, rose again from the dead on the third day,
ascended into heaven and is seated at the right hand of God the Father almighty,
who will come again
to judge the living and the dead.
I believe in the Holy Spirit,
the holy, catholic Church,
the communion of saints,
the forgiveness of sins,
the resurrection of the body,
and the life everlasting. Amen.

Lord's Prayer
Our Father in heaven,Father, 
hallowed be your name.
Your kingdom come.
Your will be done, on(in) earth as it is in heaven.
Give us this day our daily bread.
And forgive us our debts, as we also have forgiven our debtors.and forgive us our sins, for we ourselves forgive everyone indebted to us.
And do not bring us to the time of trial, [Or us into temptation] but rescue us from the evil one. 
For the kingdom and the power and the glory are yours forever. Amen.
Our Father, who art in heaven,
hallowed be thy name;
thy kingdom come,
thy will be done
on earth as it is in heaven.
Give us this day our daily bread,
and forgive us our trespasses,
as we forgive those who trespass against us;
and lead us not into temptation,
but deliver us from evil.
Most Protestants conclude with the doxology:
For thine is the kingdom,
and the power, and the glory,
for ever and ever. Amen. (or...forever. Amen.)
At Mass in the Catholic Churchthe embolism is followed by:
For the kingdom,
the power and the glory are yours,
now and for ever.
