Neither rules nor doctrine have never introduced anyone to Christ.
When a person first meets the Lord, he will tend to reflect the environment of those who are discipling him. The problem is, he needs to know he should reflect the Lord.
Legalism produces legalism and polarized doctines produce polarized Christians.
I am not suggesting a lowered standard or an ecumenical compromise. The fact is, the new believer must learn to rightly divide the Word of Truth, be a pillar in the House of The Lord, recognize the Lord, and take up the Cross and follow Him.
He must be trained to be sensitive to the leading of the Spirit, which he cannot do without the Word of God. He must be loved and receive a ministry of grace. He must be taken systematically through the Bible. He should be introduced to missions. And of course, if he has no teaching of the tenants of the faith, he will not be able to be secure in the most basic doctrines and will be squishy on everything.
The problem lies when there is an effort to create cookie-cutter Christians.
If you grab a new Christian and attempt to train him in all things behavioral, you rob him of the heavenly delight of supernatural transformation.
He needs to be trained in getting to know the Lord.
In losing his life so he can find it.
In putting the other person first.
In memorizing God's Word.
In memorizing the hymns of the faith.
In giving.
In reading about the Ebenezer stones in the lives of those who have gone before.
He must learn of the universal Body and the local Body.
Most importantly, he must learn to meet with the Lord regularly.
It is rare when one who comes to the Lord sticks to the course from day one. Often there is a working out of the shedding of the old life and the taking up of The Cross.
Minister patience, and love.
He needs to know where to put his gaze.
