I came that they may have life and have it abundantly. Jesus speaks these words before the cross, they reveal His heart. The full foundation was laid at the cross and explained in the epistles.
A glance in the mirror can awaken old labels: "not enough," "too late," "too broken." But your identity in the New Covenant is not your past. You are made new. God did not repair you, He recreated you.
Abundant life does not start someday. It starts with recognizing who you already are.
