How do we find out what it is if we have no "intimacy" with Him?
We need to grow in our personal relations with Christ through faith to have any "intimacy" How does one grow in faith?
So then faith comes by hearing, and hearing by the word of God.
Keep in mind that hearing is the only means which scripture used to be passed from one to another in those days., Today, we have His word provided for us to read, study and meditate on.
What does this faith produce? We find that answer in 2 Peter 1:5-11
But also for this very reason, giving all diligence, add to your faith virtue, to virtue knowledge, to knowledge self-control, to self-control perseverance, to perseverance godliness, to godliness brotherly kindness, and to brotherly kindness love. For if these things are yours and abound, you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins.
Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble; for so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ.
