It’s not about religion, it’s about ‘relationship’!

Not exactly.

James 2:26
26 For as the body without the spirit is dead, so faith without works is dead also.

Religion is not at odds with Justification; Religion is a fruit of justification.

Ryle writes:

“Prove it by the Sunday. Is that day a time of fatigue and pressure, or a delight and refreshment, and a sweet anticipation of the rest to come in heaven? Prove it by the public means of grace. What are your feelings about public prayer and public praise, about the public preaching of God’s Word, and the administration of the Lord’s Supper? Are they things to which you give a cold assent, and tolerate them as proper and correct? Or, are they things in which you take pleasure, and without which you could not be happy? Prove it, finally, by your feelings about private means of grace. Do you find it essential to your comfort to read the Bible regularly in private, and to speak to God in prayer? Or, do you find these practices boring, and either slight them, or neglect them altogether? These questions deserve your attention. If means of grace, whether public or private, are not as necessary to your soul as food and drink are to your body, you may well doubt whether your religion is “authentic.”
