Joshua 24:15 (NIV)

¹⁵ But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.”

Anne Graham Lotz - Jesus In Me

"One thing I know for certain: The Holy Spirit is not an optional extra in my Christian life. He is a divine necessity."

Acts 1:3-8 (NIV)

³ After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God. ⁴ On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. ⁵ For John baptized with water, but in a few days you will be baptized with the Holy Spirit.”

⁶ Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”

⁷ He said to them: “It is not for you to know the times or dates the Father has set by his own authority. ⁸ But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”

Ephesians 1:18-20 (NIV)

¹⁸ I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, ¹⁹ and his incomparably great power for us who believe. That power is the same as the mighty strength ²⁰ he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms,

Isaiah 40:28-31 (NIV)

²⁸ Do you not know?
    Have you not heard?
The Lord is the everlasting God,
    the Creator of the ends of the earth.
He will not grow tired or weary,
    and his understanding no one can fathom.
²⁹ He gives strength to the weary
    and increases the power of the weak.
³⁰ Even youths grow tired and weary,
    and young men stumble and fall;
³¹ but those who hope in the Lord
    will renew their strength.
They will soar on wings like eagles;
    they will run and not grow weary,
    they will walk and not be faint.

Deuteronomy 31:8 (NIV)

⁸ The Lord himself goes before you and will be with you; he will never leave you nor forsake you. Do not be afraid; do not be discouraged.”

Deuteronomy 31:12 (NIV)

¹² Assemble the people—men, women and children, and the foreigners residing in your towns—so they can listen and learn to fear the Lord your God and follow carefully all the words of this law.

2 Timothy 3:14-17 (NIV)

¹⁴ But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it, ¹⁵ and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. ¹⁶ All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, ¹⁷ so that the servant of God may be thoroughly equipped for every good work.

Ephesians 2:8-10 (NIV)

⁸ For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— ⁹ not by works, so that no one can boast. ¹⁰ For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.
