In the beginning, God created man to have a relationship with us for eternity. When Adam and Eve disobeyed God, we were no longer righteous by Him and became carnal and spiritually disconnected from God. Eternal life in the spiritual realm ended for man (Gen.2:17).
As time went on, the gap between a holy God and sinful man widened, a relationship hindered because we did not know His ways and thus sin and corruption filled the earth (Gen.6:5). From Adam to Moses, generations returned to earth as dust, unable to go back to God in eternal life (Rom.5:14).
God loved us and still wanted a relationship with us but being full of sin and unrighteousness, how could we draw close to a holy God again? Thus, God gave us His requirements to live by so that we would understand what sin is.
The Israelites agreed to follow God's ways by a blood covenant (Ex.24:7-8). This is like an oath or promise, sealed by the blood of bulls or goats (Heb.10:4). But they kept walking contrary to God's ways, breaking the covenant and so kept sacrificing animals to atone their sins (Isa.1:11-17) They were trying to be righteous by works instead of learning or changing from the heart and perfected the art of animal sacrifice instead of perfecting their walk with God.
Now God knew that we could not attain His righteousness in our own strength, so God spilled the blood of His son Jesus Christ, the most perfect and unblemished lamb to atone for all sins forever, putting an end to ineffectual and religious practices. Jesus died so that His Holy Spirit could be shed for us in a new covenant (Rom.5:5) where God puts His laws into our hearts and mind so that we may become of His righteousness by the Holy Spirit and not by religious works (Heb.10:16-18, Titus.3:5).
God loved us from the beginning; while Adam’s sin separated us from Him, God made it possible, by the ultimate sacrifice of His blameless son, that we might return to Him in eternity (Rom.5:19). God is not interested in religious rituals. He wants a relationship with you. His arm is still stretched out today (Ps.136:12) to receive all who will change from the heart, turn back to Him and walk in His ways (Luk.15:11-31). God’s love.
