Just as gravity is a fundamental law here on earth, so is faith a fundamental law in God’s kingdom. And you are a citizen of God’s kingdom since the acceptance of Jesus as your Savior who makes you holy before God (Philippians 3:20).
You should become increasingly aware of the power of faith because:
“But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.” (Hebrews 11:6; KJV)
Through faith, put yourself in your spirit (your perfect and holy true self ever since your acceptance of Jesus’ finished work on the cross). Make faith your victorious power. For this also applies to you: “For every child of God defeats this evil world, and we achieve this victory through our faith.” (1 John 5:4; NLT)
Tell your soul (thoughts, feelings, memories) and your body what the truth of God’s Word says through your faith. No longer vice versa. Example: Your body is moaning, ‘oh, I feel so weak.’ Through faith, you say, “No, God makes each of my body’s cells perfectly healthy and functional.”
The basis of your faith is God’s Word. You can trust God’s promises.
“Now faith is confidence in what we hope for and assurance about what we do not see.” (Hebrews 11:1; NIV)
Battery is empty?
You feel empty and burned out. You believe God’s promise that He will give you fresh strength every day (“So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand.” – God in Isaiah 41:10; NIV).
Do not be afraid of old age
You are getting older and earthly-worldly thinking wants to scare you of getting old. You believe God’s promise that you are not only full of vigor in your old age, but also bear plenty of fruit: “For they are transplanted to the Lord’s own house. They flourish in the courts of our God. Even in old age they will still produce fruit; they will remain vital and green. They will declare, ‘The Lord is just! He is my rock! There is no evil in him!'” (Psalm 92:13-15; NLT)
