There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.

1 Corinthians 10:13 KJV

Psalms 147:3 New International Version (NIV)

He heals the brokenhearted
    and binds up their wounds.

When a band-aid is used to heal the hurt and pain from the wounds of yesterday it leaves a scar to remind us of the past. The bandage will heal the wound but the scar will not let us forget.
