There are many spiritual laws that are written in scripture. Here are just a few:
Draw near to God and He will draw near to you.
(from James 4:8)
Give, and it shall be given unto you; good measure, pressed down, and shaken together,
and running over, shall men give into your bosom.
For with the same measure that ye mete withal it shall be measured to you again.
Luke 6:38
For if ye forgive men their trespasses, your heavenly Father will also forgive you:
But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Matthew 6L14-15
Whosoever therefore shall break one of these least commandments, and shall teach men so,
he shall be called the least in the kingdom of heaven:
but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. Matthew 5:19
And we know that all things work together for good to them that love God,
to them who are the called according to His purpose.
Romans 8:28
Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Galatians 6:7
If we confess our sins, He is faithful and just to forgive us our sins,
and to cleanse us from all unrighteousness.
1 John 1:9
Not everything you read in the bible will be applicable to you.
Sometimes the Lord spoke specific promises to specific people.
The Holy Spirit will help you differentiate from promises for all or specific promises for specific people. Who knows? He might give you that specific promise you desire.
Here is one for an example:
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. Acts 16:31
There are countless people of God whose entire houses were not saved both in the bible and in current times. So, that is a promise or a law spoken for those people, not necessarily for everyone. That does not mean it is not for you. That would be between you and God.
