In the Bible the ability to see is not the same as physically seeing. To see spiritually is to see life as it really is, to see life as God sees it.
The Beatitudes, spoken by Jesus Christ in his Sermon on the Mount, gives Christians God’s perspective on human situations, and on true holiness.
Blessed are the pure in heart: for they shall see God. Matthew 5:8
There is, however, a problem with spiritually seeing. First, humans are so indoctrinated and ingrained with earthly thinking that their ears are hardened and their eyes are blind that they cannot see or ear.
Open thou mine eyes, that I may behold wondrous things out of thy law. Psalm 119:18
For the LORD has poured out on you the spirit of deep sleep, and has closed your eyes: the prophets and your rulers, the seers has he covered. And the vision of all is become to you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray you: and he said, I cannot; for it is sealed: And the book is delivered to him that is not learned, saying, Read this, I pray you: and he said, I am not learned.– Isaiah 29:11
And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind. And some of the Pharisees which were with him heard these words, and said to him, Are we blind also? Jesus said to them, If you were blind, you should have no sin: but now you say, We see; therefore your sin remains. John 9: 39-41
Secondly, humans are forgetful. Spiritual truths are so alien to human thinking that those who have glimpsed the truth must constantly mindfully fervently hold onto them. This is accomplished by fellowship and friendships with like-minded believers and with daily Bible reading.
For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. Isaiah 55:8
But be you doers of the word, and not hearers only, deceiving your own selves. For if any be a hearer of the word, and not a doer, he is like to a man beholding his natural face in a glass: For he beholds himself, and goes his way, and straightway forgets what manner of man he was. … James 1:23
Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. Hebrews 10:25
Thirdly, humans often judge matters from their own limited, biased, or sinful perspectives and become confused as to the truths and affirmations of the gospel. If they are not careful, believers will think they know more than they do. Or they will belittle the Great Work of Salvation that Christ has done. Events in the world and human trials often confuse the believer who might be in danger of thinking that Christ has not accomplished as much as Scripture says he did.
Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye. Mark 7:13
For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. 1 Corinthians 13:12
You made him a little lower than the angels; you crowned him with glory and honor, and did set him over the works of your hands: You have put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him. But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honor; that he by the grace of God should taste death for every man Hebrews 2:7-9
Christians are to remember that they have many Blessed Hopes. There is the hope of seeing God, and God’s power in this world and in the next. There is the hope of the resurrection of the dead, and there is the hope of being like God and seeing Him face to face.
Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears, we shall be like him, for we shall see him as he is. 1 John 3:2
And we all, who with unveiled faces contemplate the Lord’s glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit. 2 Corinthians 3:18
I had fainted, unless I had believed to see the goodness of the LORD in the land of the living. Psalm 27:13
Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Titus 2:13
But I would not have you to be ignorant, brothers, concerning them which are asleep, that you sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 1 Thessalonias 4:13-14
The Christians is urged to hold on to true spiritual sight and true spiritual understanding. The Christian is urged to meditate on Scriptures and to be spiritually awake and mindful. In seeing matters as they really are — as God sees them– the Christian is protected against fear, doubt and despair.
For they that sleep sleep in the night; and they that be drunken are drunken in the night. But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. 1 Thessalonians 5:7,8
