Proverbs 22:5 New King James Version (NKJV)
5 Thorns and snares are in the way of the perverse; He who guards his soul will be far from them
There is always going to be someone or something who wants to stop you from moving forward. They will try to impede you by being a snare. You are to protect your heart and mind by not letting those things enter in. Although it is a fact and you see it happening, you do not have to entertain it.
Ephesian 6:16-17 NKJV
16 Above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. 17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God.
Guard your heart and look to future, you can not change your past.
