We are all born into sin. Try as we might, we all fall short, we all sin (Romans 3:23). Because of our sin, we deserve death (Romans 6:23). Without Jesus Christ, we are spiritually dead. But once we come to know Him and enter into a relationship with Him, we are no longer spiritually dead; instead, by grace, we are given life; so we die to ourselves daily and are dead to the world, but we are fully alive in Jesus (Ephesians 2:4-5). Essentially, we are dead men, walking.
However, being fully alive in Christ is not simple. It requires transformation (2 Corinthians 5:17). If our natural selves desire sin but we are saved through faith, we are pitted in a constant battle against sin. We are called to die to ourselves (Luke 9:23) - to put down everything our flesh desires, everything that is natural to us - so that we may put on Christ and be justified through Him.
We battle not against flesh and blood (Ephesians 6:12). But even when things are so difficult and temptation is so strong, we must not conform (Romans 12:2). In everything we do, we must lower our pride and surrender it all to the One who saves us (Psalm 55:22). Do not be discouraged in this crusade. The Lord your God is with you wherever you go (Joshua 1:9).
Do not lost hope, brothers and sisters. This battle we face every day is tough and wearing, but we have God on our side. He will pull us through our mud, he will mold us into something beautiful.
peace, love, and life.
