Life is spiritual. Don't forget, the spiritual gave birth to the natural. The Bible says, "In the beginning God created the heaven and the earth" (Genesis 1:1). Who created Heaven and Earth? God. That means the Earth was created; there was a day when there was no Earth, and a day when there was no Heaven. But God had always been there.
God had to be there to create everything else, and the Bible says, "God is a Spirit..." (John 4:24). This shows that the spiritual world pre-existed the natural world. The spiritual gave birth to the natural, and in that spiritual world, the destinies of men are controlled.
Life is not hard. The reason life seems hard is because a lot of people who are suffering on Earth are those who don't function in the spirit. You can't control life in the natural realm. The Bible says, "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world..." (Ephesians 6:12). Life is spiritual, and it is controlled from the spiritual realm. That's why I feel sorry for people—especially young people—who only know their books in school. You can get all the A1 you want; have twenty A's out of nine subjects, but if you don't know how to control life in the realm of the Spirit, you will still be a victim and struggle through life.
Even one small demon from your village can sit on your certificate, and with all your investment in that certificate, you won't be able to achieve anything in life. Success in life is not based on grades in school. But by the principles of God's word. So while you learn accounting, medicine, law, or any other field of study, also learn spiritual principles. And you don't learn spiritual life from a witch doctor—you learn from the Bible. The Bible says, "In the beginning was the Word, and the Word was with God, and the Word was God... All things were made by him; and without him was not any thing made that was made" (John 1:1,3). John gave the Word a personality. That means everything in life came from the Word. The Word is the source of all things.
Everything you see in nature came from the Spirit, and everything in the Spirit responds to the Word of God. So learn to live by the Word, in so doing, you will have unending success.
