In more recent decades, the concept of "social justice" (which is absolutely not the same as Biblical justice, see the book Why Social Justice Is Not Biblical Justice) has infected many Christian Churches. Likewise, "environmental justice" - another non-Biblical concept - has also gained traction in many Churches, Today, most pastors and other leaders have embraced social and environmental justice out of a desire to fit in with the modern world (though they would call it being "relevant" and "authentic" - two buzz words of the Far Left).
This desire to "fit in with the world" is condemned in Scripture many, many times. Yet, many modern Christians try to adopt worldly ways, thinking it is okay because they are giving it a supposedly "Christian" spin. It is not okay. We are followers of The Way, not followers of The World. We are called to be set-apart, not to fit in.
God, and God alone, decides what is right and what is wrong, what is sin and what is not, what is good and what is evil. What God has decided is never "out dated" or "old fashioned." We have not "out grown" what God has revealed to us. We do not become "relevant" or "authentic" by rejecting God's Laws. The world may praise us for doing so, but God won't.
Let me be clear on this: God decides what love is, not us. God decides how we are to love Him. God decides how we are to love others. We don't decide this for ourselves. God tells us exactly how we are to love Him, and how we are to Love others. It is NOT up to us to decide how we will love Him, or how we will love others. God has already decided this for us. Read the scriptures. Its all laid out right there.
Worldly ways are not God's ways, and slapping a Christian bumper sticker on it won't change that fact. Follow God, not the World. Reject modern "Christianity" that tries to fir in with the World. Reject churches, pastors, and teachers that worry more about being seen as relevant than about pleasing God.
