The noun "hope," when used in the New Testament, does not imply a wishful attitude, but rather a joyous and confident expectation in something promised which will certainly come to pass--in most cases, something good. Note especially the few times it is used with a descriptive adjective.
First, in a stirring benediction, Paul tells us that our good hope comes from both "our Lord Jesus Christ himself, and God, even our Father" (2 Thessalonians 2:16). Furthermore, such hope is given to us along with "everlasting consolation," or comfort, which shall last forever. The Father and Son have done this "through grace" which brings eternal salvation.
Next, we are taught that we should be "looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ" (Titus 2:13). This blessed hope can be none other than "our Saviour, and Lord Jesus Christ, which is our hope" (1 Timothy 1:1). He will certainly return, and this return will be glorious.
Furthermore, we have a hope which is actively alive. "The God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead" (1 Peter 1:3). We have been (past tense) born again from the dead just as surely as Christ has been raised from the dead, for His resurrection accomplished it.
Our hope, under grace, is guaranteed by Jesus Christ: "A better hope . . . by the which we draw nigh unto God" (Hebrews 7:19), than that which was possible under law. In fact, it is a glorious hope (2 Corinthians 3:11-12) by comparison. This kind of hope can be "an anchor of the soul." JDM http://www.icr.org/article/5609/
