Our actions are what determine our personality and daily we are acted before life through our ideas and thoughts.
So the actions are nothing more than actions of what we really carry inside, that is, in the heart and therefore our reactions are the responses of what we are constantly receiving or receiving or what we are sowing.
Galatians 6: 7-10
7 Do not fool yourself; God cannot be mocked: for everything that man sows, that will also reap.
8 For he who sows to his flesh will of the flesh reap corruption; But he who sows to the Spirit will of the Spirit reap eternal life.
9 Let us not get tired of doing good; because in his time we will reap, if we do not faint.
10 So, as we have the opportunity, let us do good to all, and mostly to those of the family of faith. (Reina-Valera 1960 (RVR1960)
The Bible shows us that if we sow to the flesh our actions will obviously be actions directed to sin and they will eventually bring a daunting and very regrettable effect.
Our actions will lead us to react to what we are sowing and according to the sowing we will obtain the fruits because no one in this life will be challenged of what sows each thing has its effect for better or for worse.
Humanity can act as it sees fit and they can do everything they want but they must also know that all the things we do we have to answer before God.
So we must take care of our actions if we want to have a good effect.
