Having good thoughts is not about thinking positively, nor practicing any type of mind work, good thoughts are something else, which is biblical and comes from God.
Jeremiah 29:11 11 For I know the thoughts that I think toward you, says the Lord, thoughts of peace, and not of evil, to give you the end you hope for.
We must live thinking how Jesus would do it, therefore we must take our mind captive to the thoughts of Jesus, because this will allow what is generated in our mind to be only good thoughts that make us and grow to be better every day.
God has good thoughts for us, so our thoughts should also be like that, always believing and trusting in God, our mind is the room where the plans of our life are generated, where everything that we will later put into action is born. It is not about thoughts, it is about God, about thinking as He would, good thoughts, in everything that is pure and honest, in what comes from Him, that brings us closer to Him and makes us protagonists of His blessings. . Open the trunk of your mind And allow those thoughts that do not let you advance and prosper to fly and welcome a new path, proceed to create new thoughts, allow your mind to be a place where God dwells, where He can install His Holy Spirit and that life and hope sprang from her.
Flood your mind and heart with God and it will be full of good thoughts, that is what God wants, that we lead a life where its fruits are real, genuine and conquerors of other lives.
