Awake and alive

Now I lay me down to sleep
I pray thee Lord my soul to keep
And should I die before I wake
I pray thee Lord my soul to take

~

Now I lay me down to sleep,
I pray the Lord my soul to keep,
Lord, be with me through the night
And keep me 'til the morning light.

If I should live for other days,
I pray the Lord to guide my ways.

When in the morning light I wake,
Teach me the path of love to take.

Guard me through the night,
And wake me with the morning light.

Thy angels watch me through the night,
And keep me safe till morning's light.

Keep me safe all through the night,
And wake me with the morning light.

Guide me safely through the night,
Wake me with the morning's light.

See me safely through the night,
And wake me with the morning's light.

Guide me through the starry night,
Wake me when the sun shines bright.

Guide us through the starry night,
and wake us with the morning's light.

I ask not for myself alone,
but for thy children—every one.

May angels watch me through the night,
And keep me in their blessed sight.
Thank you for another day,
A chance to learn, a chance to play.

God bless those who are so dear
And thank you lord for all good cheer.

May angels watch me through the night,
And keep me in their pleasant sight,

This is a classic English children's prayer from the 18th century. It's a Christian one but it's still nice. These are various versions of it.
