Your foundation is in Jesus Christ
The Israelites’ standing before God in the Old Testament was wrapped up in the standing of their high priest. That meant that how the high priest was before God was the same for the entire nation. If the high priest sinned, he brought guilt on his nation, and God would reject the entire nation no matter how law-abiding the people were or how faithful they were in bringing their sacrifices.
In the same way, if the high priest was without fault and acceptable to God, the whole nation would be acceptable, even if the people were sinful.
The high priests of Israel often failed because like any human being, they were not perfect but fortunately for us Jesus is our high priest. Jesus who is 100 per cent Man and 100 per cent God is our high priest, standing before God, interceding on our behalf. Jesus is always acceptable and pleasing to the Father. Therefore, we can never lose our acceptance with God because as our High Priest, Jesus only brings righteousness on His people.
In heaven right now, Jesus our High Priest is seated at the right hand of God the Father (Romans 8:34). This means that God does not look at you and I. He looks at Jesus only. If Jesus is good, you are good. If Jesus is accepted, you are accepted. If God sees Jesus perfect, then He sees you perfect. If Jesus is righteous, then you are righteous. And we know that Jesus our High Priest is good, accepted, perfect and righteous, which means that that is how God sees us!
We cannot lose our right standing before God because Jesus Christ is our high priest. Jesus would have to lose His standing first before we can lose ours. But we know that we have in Jesus a High Priest who is perfect and who cannot fail. So you need never be afraid or conscious of your faults when you come before God. Because your standing is completely wrapped up in Jesus your High Priest, you can come to God boldly and receive all that you need from Him!
