It is important that we trust in God, because God is the one who sustains us and helps us to stand, it is good to remember that without Him we are nothing and we can not do anything, our lives must always be placed in the hands of the Almighty God.
The strong and courageous God will defend us and keep us from the evil one, no matter who rises up against us. God will fight for you and will defeat and take away everything that makes you or wants to make you the war.
May they be like chaff before the wind,
with the angel of the Lord driving them away;
God is always attentive, He defends His children, cares for them and shows them the way to salvation. The angel of the Lord defends us and removes all obstacles, the evil one is waiting us to fall in order to point us with the accusing finger.
may their path be dark and slippery,
with the angel of the Lord pursuing them.
The psalmist saw the wickedness of these men, then seeing their wickedness he then declared these words saying, that their way be of darkness and that in a moment fell on the slip, and that the angel of the Lord pursued him in all his way.
Since they hid their net for me without cause
and without cause dug a pit for me,
This man had a nice heart and showed mercy to other people no matter what they had done, but there were also those who envied him and wanted to kill him. But God never departed from him, He was always ready to help him and to destroy his adversaries.
So if we trust in God everything will turn out well, because everyone who has his trust placed in the almighty God, will be good all the time, God is our helper, our strength, He is our early help in the tribulations. Believe in Him and He will do, the God who cared for the psalmist David will also take care of you.
