Difference in the Atonement and Purification Blood of Christ.

Numbers 19:14 describes how when someone dies in a tent, anyone who enters the tent and everything inside becomes unclean for seven days. This highlights the concept of uncleanness, which comes from merely being in the presence of death. In our world, believers are exposed to sin and uncleanness, and thus must continually seek purification through Christ, paralleling the red heifer's symbolism.

Isaiah 6:5-7 gives an example of Isaiah recognizing his unclean state before God and being cleansed by a live coal, symbolizing forgiveness and purification. Similarly, in 1 John 1:7-10, believers are reminded of the need to walk in the light and confess sins to maintain fellowship with God, as He cleanses us from unrighteousness.

It's important for believers to purify themselves not for salvation, which is secured through Christ’s sacrifice (as Hebrews 9:12 highlights), but for ongoing fellowship with God. Salvation is a one-time event through faith in Christ’s atoning blood, granting eternal life. Purification, however, is part of our daily walk with God, ensuring that we can serve and connect with Him.

In Romans 7, Paul touches on the struggle between the desires of the flesh and the desire to serve God, emphasizing that while salvation is secure, believers must actively seek spiritual cleansing to overcome the limitations in their flesh. This cleansing cultivates a clear conscience and strengthens the believer's fellowship and service to God.
