You have to continue the process of renewing your mind, because even though your spirit has been saved when you give your life to Christ, your body and mind still reside here on earth, in this fallen world where Satan is on the rampage.
Remember how after the Israelites left Egypt they kept desiring to go back, and they even manifested the ways, and behaviors of the Egyptians a number of times (Exodus 16:2-3, Numbers 14:1-4)? That is because even though they had left Egypt physically, they hadn’t left Egypt mentally!
They hadn’t renewed their minds enough to be able to see and enjoy the new life and the newer, bigger, and better picture God had in store for them! This is what happens when a person is still torn between the things of God, and the things of the world even after they’ve been saved.
The word of God tells us to be “transformed by the renewing of our minds” (Romans 12:2), and as you do this you realize that life is so much better than you could’ve ever imagined. That all the battles you face now, can not compare to the glory that shall be revealed in us.
May the Holy Spirit continue to strengthen you as you follow Jesus with everything in you, and continue your journey to be all that you’re called to be!
