Far too many believe the words “If ignorance is bliss, ’tis folly to be wise”; refusing to engage the mind into deeper thought and reflection on the things of God. To suppose that all one needs is to believe in the existence of God, and have a basic understanding of the foundational doctrine, one may assuredly not assume the stance of a strong Christian, but rather of immature Christian feasting on spiritual milk. (Hebrews 5:12-14) In the beginning, this is what all need, but soon, our growing spirits need more advanced nourishment by means of study and reflection.
Effort must be made on every individual’s part to grow spirit. Spiritual leaders may assist us in this quest, yet, one mustn’t depend on others for growth; but rather to constantly be checking and affirming such teachings against the Word. (2 Peter 2: 1) Do not be led astray by the vain and meaningless teachings of man, prone to corruption and inaccuracy, but rather lean on Christ Himself, for He is the Word.
In the beginning, the Word was with God, and the Word was God. (John 1:1) By studying Scripture, we are indeed studying God. However, beware the fate of those who treat the Lord of all Creation as a mere matter to be studied. He is also fully a person, able to relate to the struggles of humanity. This is something incomprehensible (1 Timothy 3:16), as no amount of study will reveal why He chose to come down from His majesty to redeem our sinful souls and to care. His complexity cannot be understood in a complete form, but rather only in part by faith.
A simple mind will not even attempt to understand that which is understandable of God, which has been revealed to us in Scripture. Instead, the simple depend too much on blind trust, lacking wisdom and prudence in their journey of life. Under the premise that faith is all one need, in a sense of trust, one misidentifies what faith is. Assuredly, faith is not a scapegoat for our laziness, but rather is an act of trust and of deeds. For faith without works is dead. (James 2:17)
On a different point, there are yet some that a highly intelligent, but still posses a simple mind. Engaging in meaningless quarrels over various topics of the law and causing chaos where none was previously. (Titus 3:9) They may engage in a deep intellectual study of the Scripture, but cease to have an inward conviction of its truth. For we ought not to elevate our understanding of God and the law that we may “win” arguments and debates. For it is entirely the power of the Gospel that converts the soul, not human attempts of rationality. (1 Corinthians 1:17) These people may be prone to answering fools with the same means to fool used to attack them (Proverbs 26:4), which is absurd, as we know that our battle is not fought with the weapons of this world (Ephesians 6:12). One may have a simple mind and still be a true believer, but very young one.
