We are called to live by faith, rather than relying on what we can see.
We walk by faith, not by sight (2 Cor 5:7)
So Christians should aim to see in the spirit by faith, rather than needing to see the spiritual realms with our physical eyes.The Spirit searches all things, even the deep things of God. For who knows a person’s thoughts except their own spirit within them? In the same way no one knows the thoughts of God except the Spirit of God. What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us. This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, explaining spiritual realities with Spirit-taught words (1 Cor 2:10-13).
In most situations, seeing in the Spirit by faith should be sufficient. It requires faith, but that it is good because God wants us to grow in faith.
We are to walk by faith and not by sight, so in principle seeing and hearing in the Spirit should be enough. However, God is not stingy, so he gives us more when we need it, or just when he wants to bless us. There are several reasons why a person might get more intense perception revelation of the spiritual realms.
A common reason is corrective. Our world has become so secular and materialistic that we are almost ignorant of the spiritual realms, and most Christians lack the ability to discern them. God is allowing some Christians to see the spiritual realms physically, so they can communicate clearly what is happening to make his people hungry and open their minds to what they are missing. This seems to be the case with Brad Healy. He sees amazing details. It took quite a while, but he eventually came to understand that his purpose was to help other Christians see and understand the spiritual realms. He seems to be committed to helping Christians see in the Spirit more clearly.
Our understanding of the spiritual realms is so limited that we need descriptions by people who seen their working clearly to open our minds. Christians should be taught about the operation of the spiritual realms as soon as they come to faith. Most have not had this teaching. We need this understanding to become normal again. People who have seen vividly can help with this restoration.
When we have a big costly decision to make, God can give a more intense revelation, so that we can be certain of what he has asked us to do. Joseph is an example. God sent an angel to him in a dream. Through the dream, he knew exactly what God wanted him to do, even though he was not skilled in hearing and obeying the Spirit. He could not have this skill, because the Spirit has not yet been poured out.
People called to a task that is really critical for God’s plan may get very clear perception and direction. Mary spoke with an angel face-to-face. A young woman caring for a baby conceived by the Holy Spirit would need tremendous faith. Receiving such a vivid and real communication would have built her faith. Mary was wise and fed her spirit by treasuring her experience in her heart.
Abraham saw three angels. This dramatic encounter would have contributed to his faith and enabled him to trust God’s promise and move to a new land where he did not belong.
Many prophets were given an open vision at the beginning of their ministry as part of their calling. Elisha saw Elijah go up to heaven (2 Kings 2). Jeremiah saw a vision of an almond tree (Jer 1). Isaiah received a vision of angels (Is 6).
When prophets receive vision for way in the future, God sometimes give clear physical vision. The prophet is often called to prophesy about things so far in the future that they cannot even imagine the situation. God has to use powerful physical revelation to break that barrier. The Revelation of John is an example. John probably thought that he understood some of what he saw. But he could not even imagine the world in which some of it will be fulfilled. God gave the vision to him in a way that his mind could see and record, without needing the background understanding.
God will sometimes send intense revelation to sustain people who are being persecuted for their faith. We do not know when it occurred, but Paul had an experience where he went in the third heaven (also known as paradise). He saw things he could not speak about. This event would have sustained him through his frustration and loneliness during this may years of persecution in Roman jails.
Stephen was given an open vision of Jesus seated at the right hand of God when he needed the faith to face martyrdom (Acts 7:55-57).
When people are afraid, God sometimes gives a powerful and clear vision of the spiritual reams to increase their confidence. Elisha’s servant is an example, he was afraid of the enemy army, so God gave him and open vision of the spiritual forces arrayed against it (2 Kings 6:15-17).
When people have been hurt by traumatic experiences, they can find it hard to accept that God loves. Sometimes a powerful vision of Jesus, where they can see his love is needed to open their hearts.
Spiritual visions are a quick way of understanding the cause of the problems carried by people who come to us for ministry, especially if we do not know them. God can expose the root of the problem in a spiritual revelation.
Children sometime see into the spiritual realms very clearly, because they have not yet learnt to ignore them. John the Baptist had a physical experience of Jesus when has still in the womb. Children growing up in Christian families should learn about the spiritual realms from their parents, as they are growing up. I suspect that many would get insight quickly. I presume that many children experience things that parents think are quaint, such as invisible friends, which are really experiences of the spiritual realms. Parents should help their children to get a broader understanding of the spiritual realms in which they live, rather than just laughing.
Seeing by faith is probably better than seeing by sight. However pretending to see by faith, when you are really walking in darkness is foolish. We need a lot more of both seeing by sigh and seeing by faith. We will need a lot more seeing by sight before God’s people are proficient at seeing the spiritual realms in the spirit by faith.
