Scripture reveals the reasons why believers accept Jesus as the Son of God.
And a voice from heaven said, "This is my Son, whom I love; with him I am well pleased." Matthew 3:17 NIV
God has now revealed to us his mysterious plan regarding Christ, a plan to fulfill his own good pleasure. And this is the plan: At the right time he will bring everything together under the authority of Christ—everything in heaven and on earth. Furthermore, because we are united with Christ, we have received an inheritance from God, for he chose us in advance, and he makes everything work out according to his plan. Ephesians 1:9-11 NLT
Jesus is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. 17He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. 19For God was pleased to have all his fullness dwell in him, 20and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross. Colossians 1:15-20 NLT
All praise to God, the Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly realms because we are united with Christ. Even before he made the world, God loved us and chose us in Christ to be holy and without fault in his eyes. God decided in advance to adopt us into his own family by bringing us to himself through Jesus Christ. This is what he wanted to do, and it gave him great pleasure. So we praise God for the glorious grace he has poured out on us who belong to his dear Son. He is so rich in kindness and grace that he purchased our freedom with the blood of his Son and forgave our sins. 8 He has showered his kindness on us, along with all wisdom and understanding. Ephesians 1:3-7 NLT
...God is so rich in mercy, and he loved us so much, that even though we were dead because of our sins, he gave us life when he raised Christ from the dead. (It is only by God’s grace that you have been saved!) For he raised us from the dead along with Christ and seated us with him in the heavenly realms because we are united with Christ Jesus. So God can point to us in all future ages as examples of the incredible wealth of his grace and kindness toward us, as shown in all he has done for us who are united with Christ Jesus. God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. Salvation is not a reward for the good things we have done, so none of us can boast about it. For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago. Ephesians 2:4-10 NLT
What shall we say about such wonderful things as these? If God is for us, who can ever be against us? Since he did not spare even his own Son but gave him up for us all, won’t he also give us everything else? Who dares accuse us whom God has chosen for his own? No one—for God himself has given us right standing with himself. Who then will condemn us? No one—for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God’s right hand, pleading for us. Can anything ever separate us from Christ’s love? Does it mean he no longer loves us if we have trouble or calamity, or are persecuted, or hungry, or destitute, or in danger, or threatened with death? No, despite all these things, overwhelming victory is ours through Christ, who loved us. And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love. No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord. Romans 8: 31-39 NLT
