If you can find what God's word says about what you want and align yourself with it, He will be committed to doing His part.
Promotion comes from God (Psalm 75:6-7), He decides whom to raise and whom to bring down (1 Samuel 2:7-8). Yet you can get God to promote you (fulfilling His word) by being humble. (1 Peter 5:6)
If you are diligent in your business, you will stand before kings (Proverbs 22:29). Hence, to get to the very top and bear rule, you must add diligence to your humility. (Proverbs 12:24).
The devil knows that God will not go against His word, so he tempts you into committing sin, and accuses you before God. (Revelation 12:10)
“Never give the devil the opportunity to use God's word against you, rather, use God's word to your favour by always praying and doing according to His will.”
Memorise: I will worship toward thy holy temple, and praise thy name for thy lovingkindness and for thy truth: for thou hast magnified thy word above all thy name. (Psalm 138:2)
