The "hope of Israel" (Ac 28:20) is "the promise to which our twelve tribes hope to attain" (26:7). It is the "hope of the promise made by God to our fathers" (:6) regarding "the hope of eternal life, which God, who cannot lie, promised long ages ago" (Titus 1:2). God has "given us eternal comfort and good hope by grace" (2Th 2:16) and we are "made heirs according to the hope of eternal life" (Titus 3:7). "There is one body and one Spirit, just as also you were called in one hope of your calling" (Eph 4:4). Paul prayed "that the eyes of your heart may be enlightened, so that you will know what is the hope of His calling" (2:12).
How do you have hope? Hoping must be directed properly. It is necessary to "hope in God" (Ac 24:15) and to "hope in Christ" (Eph 1:12) because it is "Christ Jesus, who is our hope" (1Ti 1:1). Next we are to "take hold of the hope set before us" (Heb 3:18) and then your "flesh also will live in hope" (Ac 2:26). Where is the source of hope? "In earlier times [it] was written for our instruction, so that through perseverance and the encouragement of the Scriptures we might have hope" (Ro 15:4). "Hope does not disappoint, because the love of God has been poured out within our hearts" (5:5). "In His name the Gentiles will hope" (Mt 12:21). It is "this mystery among the Gentiles, which is Christ in you, the hope of glory" (Col 1:27). There is a "hope laid up for you in heaven, of which you previously heard in the word of truth, the gospel" (:5). "This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the veil" (Heb 6:19).
What is our position? "His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead" (1Pe 1:3). "Everyone who has this hope fixed on Him purifies himself" (1Jn 3:3). "Show the same diligence so as to realize the full assurance of hope until the end" (Heb 6:11). "Therefore, prepare your minds for action, keep sober in spirit, fix your hope completely on the grace to be brought to you at the revelation of Jesus Christ" (1Pe 1:13). "If we have hoped in Christ in this life only, we are of all men most to be pitied" (1Co 15:19). Therefore be "steadfast in hope" (1Th 1:3) and "continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard, which was proclaimed in all creation" (Col 1:23). "Sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you" (1Pe 3:15).
