Philippians 3:13

Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before.

Memory: The power or process of remembering.

If your not careful, your past may become your future. If you are being bound by issues of the past, then those same issues will cause you to be bound in your life in Christ. The only way to obtain forgiveness for these things that cause you to be bound is to place them before God. Not asking for forgiveness leaves it to harbor in your life, and show up in your personal relationships. For example at work, with your children or with your family.
We as a people, if things seem to be going good for our benefit, we tend to block out everything concerning our hurts pains and anguish, right out of our minds. Sometimes we will even hold memories against one another, for the purpose of manipulating or controlling; and such is sorcery. The greek word for control or sorcery is pharmakeia which is where we get our modern word for pharmacy. Pharmakeia equals drugs, magic and witchcraft.

1 Samuel 15:23

For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou has rejected the word of the Lord, he hath also rejected thee…

Many of us have been practicing witchcraft and sorcery unbeknownst to us. If you continue to do these things they become apart of you. And it becomes a cancer that you spread to others around you. Here are a list of things associated with sorcery:

1)You’ve heard the phrase “I hate you.” The word hate or hatred in greek is echthra, meaning hostilities and bitterness. When you see this it is contrary to being a Child of Christ.
1 John 3:15
Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.

2) Jealously. The greek word for jealously is zelos meaning heat, envy, indignation, emulation, or from the term zeal which means hot or boiled.

3) Dissension. Greek word for dissension dichostasia meaning division and sedition. This word is only mentioned in the bible 3 times in the new testament. Each time it talks about sin. Division and sedition are the tools that Satan uses often; bringing something or someone into your life that causes you to have second thoughts, and in Christ, you can’t have second thoughts. He tries to divide and conquer you for the purpose of breaking you down making you give over to his will. If you are overloaded  with stress, you cant reason, and aren’t receptive to wisdom beneficial to your growth.

4) Fornication. Greek word is pornia which is sexual impurity, and where our modern word porn comes from. It can be spiritual. This includes premarital sex, homosexuality or any sexual activity outside of the sanctity of marriage.
1 Corinthians 6:15-20

5) Uncleanness. Akatharsia meaning impure or foul; demonic.
2 Corinthians 7:1
Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.

These are the questions you need to ask yourself:
a) In any situation, what is your response? Would it be pleasing to God or man? Colossians 3:23 “and whatsoever ye do, do it heartily, as to the Lord, and not unto men”
b) What would be the consequences of that situation? Galatians 6:1-18
c) Will it be a stumbling block to others? 1 Corinthians 8:1-10
d) Could you thank God for it? Colossians 3 emphases on verse 17
e) Would you be able to ask God to bless it? Proverbs 10:22
d) Would yo want to be doing this when Jesus returns?
f) Have you sought Godly council or advice?
If you answered no to any of these above, then you need to seek the face of God before you go any further.

In conclusion, it is for each child of God to walk out their faith in Him.
