Good question, @dewreeves. I would say that, aside from the general promise in II Timothy 3:16 that all scripture is profitable in various ways, the contemplation of prophecy has many practical benefits - and they are explicitly listed in the very passages that focus on Christ’s return.
For example, I John 3:2 says, Beloved, now are we the sons of God, and it doth not yet appear what we shall be, but we know that, when he shall appear, we shall be like him, for we shall see him as he is. And then the very next verse says, And every man that hath this hope in him purifieth himself even as he is pure. Without exception, every man that looks forward to the appearing of Christ purifieth himself. Learning about the end times is a motivation to be pure as Christ is.
In II Peter 3, you see the same thing. He spends the first part of the chapter giving a wealth of information about Christ’s return, then in verse 14 he says, Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot and blameless. Learning about the end times motivates us to be diligent peacemakers living spotless and blameless lives.
Again, after that famous Rapture passage in the end of I Thessalonians 4, and the description of the day of the Lord in the beginning of I Thessalonians 5, Paul says in verse 6, Therefore let us not sleep, as do others; but let us watch and be sober. So it motivates us to be watchful and alert.
And he elaborates on that phrase, be sober down in verse 8 - let us…be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. So learning about Christ’s return encourages our faith, makes us more loving, and strengthens our hope in the coming deliverance - and faith, hope and love are cardinal virtues (I Corinthians 13:13).
And he concludes that prophetic section in I Thessalonians 5:11, saying, Wherefore comfort yourselves together, and edify one another, even as also ye do. So thinking about prophecy is a source of comfort, or encouragement, as I Thessalonians 4:18 also confirms - and it serves to edify us, or build us up.
So I believe the New Testament very clearly teaches that meditating on the prophetic scriptures has abundant practical value.
I hope this will help you!
