1 Cor 2:15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
We live in an age when people are often seeking God on their own terms, wanting to receive God's blessings but not prepared to give anything in return. When we live like this we fail to grow in spiritual knowledge and are in danger of being deceived by false teachers. In the above verse Paul says that 'he that is spiritual judgeth all things'. When we look at the whole chapter it becomes clear that Paul is talking about judging spiritual things. We're not to be condeming and critising people, but we are to judge the things we hear from our spiritual leaders.
Being fooled by false teachers is nothing new. Since Christ walked this earth false 'religions' and cults have grown out of men's desire to make God fit their way of thinking. The catholic church, the mormons, the JW's, muslims, and many more groups have begun to accept first the teachings (traditions)of men above the teachings of God's Holy and innerant Word. They fail to look at scripture alone for the answers they are looking for so write their own thoughts and then say they were inspired of God.
There are many teachers today that say they come in the name of Christ yet they are teaching a false gospel. The prosperity gospel, the health and wealth movement, the signs and wonders movement - they all seek to meet God on their own terms and they twist scripture to suit their own greedy and selfish desires. Have you ever seen a poor minister of the prosperity gospel?? NO! But do they rely on God for their every need (need not want!). No! They rely on the vulnerable, those who are seeking a blessing they mistakenly think they can buy by making a donationto these people.
2 Timothy 4:3 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
We have to grow in knowledge of God in order to not be misled by these teachings. How can we do that? Easily, by becoming solidly grounded in the Word of God and by praying earnestly for the wisdom of the Spirit.
Psalm 111:10 The fear of the LORD is the beginning of wisdom; all who follow his precepts have good understanding. To him belongs eternal praise.
The beginning of wisdom is fear of the Lord. Not a terrified fear but a reverant fear. This is our awesome God and out of respect for his majesty and justness we have a reverant fear. What are His precepts? Look to scripture for these answers! God's expectations of us are all contained within His word. The Bible is the Christians rule book - not too hinder us or to bind us up but to loose us from Satan's deceitful lies so that we can be free in Christ Jesus, just as this following verse shows:-
1 Cor 6:12 All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.
So we can see that in order to grow in spiritual wisdom we have to have a fear of the Lord and we have to follow his precepts. We can only do these things if we spend time with him studying and praying so that our relationship with Him grows and our hearts and minds are made sensitive to His will. The word of God is not a mystery to those who love Him and trust in His word. He has revealed to us all that we need to know to effectively live a disciplined Christian life.
Proverbs 3:13 Happy is the man that findeth wisdom, and the man that getteth understanding.
Proverbs 4:5 Get wisdom, get understanding: forget it not; neither decline from the words of my mouth.
Proverbs 16:16 How much better is it to get wisdom than gold! and to get understanding rather to be chosen than silver!
