The inherent abilities in you that are made available by Christ in your human spirit are potentials that can only be put on display if you can willingly exercise and stir up your spirit. When you begin to exercise your spirit, you will be amazed at the head start you will have. You will realize that your situation and the problems you think you have are like that because you don't see them from God's perspective.
When you give yourself to spiritual exercise, grace will break out of your life, the hand of God will become stronger upon your spirit, and you will have clear-cut instructions from God to fulfill destiny. This is how a Believer wins, it's by exercising his spirit - he builds himself up in his most holy faith by praying in the Holy Spirit.
The reason why you feel rejected and think you are full of infirmities is because you've decided not to build your spirit. When you embrace God, He will enlarge your heart and grace will flow through it. Every pressure and things Satan throws at you will fail because you are built up in God. Every word God has said concerning you will find fulfillment and not fail because you've decided to remain plugged into God.
You are admonished to take away the complacency and repent of your old ways for the power, wisdom, and strength of God to come into you. The moment you take up the challenge to stir up the gifts of God in you by exercising your spirit always and consistently, these are the things that will manifest in your life - that is when you will know what it means to walk in the power and authority of God - this spiritual secret was revealed by Apostle Arome Osayi where he revealed the power of praying in tongues and spirit daily to the congregation: https://youtu.be/pWJW8oVMmLI?si=ZCVXB37rSS87_2V5
What a life-changing and robust sermon that will radicalize your Christian living and make you profit maximally from the Holy Spirit, exercising your spirit, prayer (in tongues and in spirit), and the power of God. It will bless you tremendously.
