If Jesus can conquer sin, death, and the grave, then He can conquer your doubts, your failures, and your weaknesses.
If the end to which we were created is to revel in joy at the glory of God, then for the doctrines of grace to land on us any other way means that we don’t quite fully understand them.
Our authenticity is proven by our persevering obedience to Jesus. In other words, like repentance and faith, perseverance is necessary for our salvation.
The Christian life is one of balance and the process of living in this balance brings tension. Living in constant tension is tiring and in a desire to bring release we can find ourselves tipping the scales in favor of one emphasis over the other. I suspect that this is the cause of much of our debate and disunity in the body of Christ, and I think we would be better served by acknowledging and being satisfied with the tension rather than seeking to relieve it.
When God desired to create something in His image, He created man. When God desired to reveal Himself in His fullness, He revealed Himself as a man. Humanity is essential in displaying who God is and that fact also says a lot about who we are.
