Every Church can and should be very very spiritual. It is not the issue whether we are too spiritual or you say "overspiritualise things". It is rather some are focusing on some or specific spiritual agenda rather than unity. We should not be too "hot" or too "cold". If you ever had occasion to drink a lukewarm soft drink, you know the feeling. The key is that we must worship God in Spirit with other believers regardless our "personal" opinion on a specific doctrine which we will often see that there will be disagreements. We are to have a spirit-filled church and spirit-filled worship.
When Jesus said John 4:23-24 "true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks. God is spirit, and his worshipers must worship in spirit and in truth." We are commanded to worship in spirit and we should be spiritual. We ought to live as direct response to spiritual transformation from the inside. We are working on spiritual attitudes of our hearts. We who know and love Him are the living church that has been born into the family of God by the Holy Spirit. As members of "the general assembly and church of the first-born, who are written in heaven" (Heb. 12:23), we have been declared righteous because our sin has been washed away by the blood of Jesus Christ (Rev. 1:5).
We have to realize that a local church's accomplishments will depend upon members' spiritual condition. If the people are submitting to the Holy Spirit, who will give them fruit. Quality is measured by the Christ-like living of a local church members. Let the Holy Spirit do what He will through you and see what He does with you. Just allow the Holy Spirit plant the desires to serve the spiritual gift or gifts and watch fellow members affirm your spritual gifts. 1 Corinthians 14:12 "So it is with you. Since you are eager to have spiritual gifts, try to excel in gifts that build up the church." The idea of the spiritual gifts is simply that the Lord uses that gift in a unity, in a unifying way. God will use our spiritual gifts by His Spirit as He wills.
Spirit-lead is outlined in Galatians 5:22-23 "The fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control." That we should "not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption." (Ephesians 4:30) That if we have any encouragement from being united with Christ, if any comfort from His love, if any fellowship with the Spirit, if any tenderness and compassion, then make our joy complete by being like-minded, having the same love, being one in spirit and purpose. (Philippians 2:1-2). Let the word of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns and spiritual songs with gratitude in your hearts to God (Colossians 3:16).
