Deuteronomy 30:15–20

15 “See, I have set before you today life and prosperity, and death and adversity;
16 in that I command you today to love the Lord your God, to walk in His ways and to keep His commandments and His statutes and His judgments, that you may live and multiply, and that the Lord your God may bless you in the land where you are entering to possess it.
17 But if your heart turns away and you will not obey, but are drawn away and worship other gods and serve them,
18 I declare to you today that you shall surely perish. You will not prolong your days in the land where you are crossing the Jordan to enter and possess it.
19 I call heaven and earth to witness against you today, that I have set before you life and death, the blessing and the curse. So choose life in order that you may live, you and your descendants,
20 by loving the Lord your God, by obeying His voice, and by holding fast to Him; for this is your life and the length of your days, that you may live in the land which the Lord swore to your fathers, to Abraham, Isaac, and Jacob, to give them.”

Joshua 24:14–15

14 “Now, therefore, fear the Lord and serve Him in sincerity and truth; and put away the gods which your fathers served beyond the River and in Egypt, and serve the Lord.
15 If it is disagreeable in your sight to serve the Lord, choose for yourselves today whom you will serve: whether the gods which your fathers served which were beyond the River, or the gods of the Amorites in whose land you are living; but as for me and my house, we will serve the Lord.”

Matthew 7:13–14

13 “Enter through the narrow gate; for the gate is wide and the way is broad that leads to destruction, and there are many who enter through it.
14 For the gate is small and the way is narrow that leads to life, and there are few who find it.”

John 3:16–18

16 “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.
17 For God did not send the Son into the world to judge the world, but that the world might be saved through Him.
18 He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God.”
