God is the reason you have a relationship with Christ Jesus. God is the reason that you are in Christ Jesus. Jesus Christ has become our wisdom from God and our righteousness and our purity and our redemption (see 1 Corinthians 1:30).
You have probably heard the saying from Isaiah 64:6, "All of our righteousness is like filthy rags." Who is that talking about? That is not talking about children of God. Our righteousness is not like filthy rags. Our righteousness is Christ's righteousness. This means we are completely acceptable to God. God sees the perfection of His Son and receives us into a relationship with Himself. Philippians 3:9 says, "I have the righteousness that comes by way of Christ’s faithfulness – a righteousness from God that is in fact based on Christ’s faithfulness."
When you love your spouse do you love him or her to the extent that you do based on their position as your spouse, that is because you have a marriage certificate? No you love your spouse because of who you see him or her to be. It is full reality to you. You consider your spouse to be wonderful and you can't be convinced otherwise.
God is the same way. He loves us based on who He sees us to be. Our lives are hidden with Jesus Christ in God. Christ is our life (see Colossians 3:3-4). 1 John 5:12 says, "God has given us eternal life, and this life is in his Son. He who has the Son has life." 1 John 4:9 says, "God has sent his one and only Son into the world so that we may live through him."
