Your spiritual senses are exercised by reason of use. You discern Christ. When you see Him, you are transfigured to be like Him.

Another way to look at this is that Truth sets us free. We each have the systems, disorders, and lies of this age in our hearts. The lies of this age blind us--we can't see. The lies in our mind keep us in bondage. These lies act as a filter so we cannot discern reality. Our actions are based our perceptions of reality. Without a vision, the people perish. Truth sets us free.
We can, theoretically, say that Christ came in the flesh, yet deny it in our actions.

Only actions that proceed from Christ are righteous. Actions that do not proceed from Christ are always unrighteous because of their source. We were created to flow with the love that comes through Christ. Without that love, the best we can be is hypocritical.

If we do not discern Christ, our actions, though seemingly good, are unrighteous since they proceed from us and not Christ. What we see makes a difference. This is the same as saying that if we glory in ourselves, then it is we who are doing the work rather than Christ. If, for instance, we come to Church and try to minister in our own power, it is not Christ who ministers, it is ourselves who minister.

When we see Christ, in our brother and our sister, we receive that ministry that proceeds from the Christ in them. This is the ministry that has power to build us up.
When we do any work that is by faith, we are actually discerning the Body of Christ, since it is a work that is of faith. That is, God speaks, we acknowledge and receive God's faith which gives access to God's grace (free gift of righteousness) which does the work in us and plants the seeds of holiness and redemption (freedom from sin) in our hearts, changing us in our very nature from glory to glory. If it is not by faith, then it is a work of us, which only can yield death. It can look good, but only that which comes from God is good and only that which comes from God transfigures us.

(some caveats about hearing God's Voice)

When we speak of being in Christ Jesus, we are really speaking of being in Christ the Body. When we speak of Christ Jesus in us, we are really speaking of having Christ, the Head, living in us and leading us and doing His work through us.

When God speaks, He doesn't always use words: "And he said, Hear now my words: If there be a prophet among you, I the LORD will make myself known to him in a vision, and will speak to him in a dream. My servant Moses is not so, who is faithful in all mine house. With him will I speak mouth to mouth, even apparently, and not in dark speeches; and the similitude of the LORD shall he behold: wherefore then were ye not afraid to speak against my servant Moses?" Numbers 12:6-8 Now, in our day, we find that God leads through the Bible, through the conscience, through members of the Body of Christ, and through many other means. “You know that when you were pagans, you were led astray to the mute [incapable of articulate speech] idols, however you were led. Therefore I want you to know that no one who is speaking by the Spirit of God says, "Jesus be cursed," and no one can say, "Jesus is Lord," except by the Holy Spirit.” (1 Corinthians 12:2-3)

The biggest lie is the lie that has a complete representation in our minds involving all of our senses. These lies are so real that we think they are reality itself; however, they are not reality. They are lies. These lies control our actions. They speak to us in contradiction to what God shows us. In each moment, when we listen to God, when we see the heavenly vision that He gives, we receive His faith, which gives access to His grace, which does His works, which leads to His holiness and redemption, which is our transfiguration. That one sentence describes exactly how each member of the Body of Christ was designed to function in the Body.

There are only two entities. There is Christ, and there is that which is not Christ. There is the church and there is that which is not the church. That which is not the church is sometimes called the world. It is that which is of the present evil age, it's orders and ideas. The word, church, means "called out." The church is simply that which has been called out of the world.
When we see anything, we discern the Body of Christ, the church. We can see that which is of Him and that which is not of Him. We can only discern this as He reveals it to us. For God to reveal a thing to us is for Him to communicate with us. So He shows us reality, what is the church and what is not the church. Our flesh tries to convince us of a lying vision. When acknowledge God rather than our own flesh, faith comes opening the door to grace which does the works in us and leads us into holiness and redemption from glory to glory.

Only God can reveal the Truth, since we cannot discern between the lies and the Truth on our own. The Church is mechanism that God primarily uses to reveal the Truth. God can and does come to us directly to reveal His will, but, as a member of the Church, He is simply preparing us for taking our places in Christ the Body in the in-Christ experience. We take our places and begin to supply the needs of every other member. God's goal is to build the entire Body according to the pattern with every gift, ministry, operation, office, and order in its place and fully functioning. Whenever the Body of Christ comes into this place of completeness and order and unity, they will call that the manifestation of the sons of God.
