Hebrews 1:3: He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power.
In knowing Jesus, we can know and understand God.
John 14:7–9: If you had known me, you would have known my Father also; and from now on you know him and have seen him. … Whoever has seen me has seen the Father.

God showed us His love by sending Jesus to earth.
Romans 5:6–8 NIV: You see, at just the right time, when we were still powerless, Christ died for the ungodly.

But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
1 John 4:9–10: In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. In this is love, not that we have loved God, but that he loved us and sent his Son to be the propitiation for our sins.
