What He has done, what He is doing, what He will do. That about covers it.
What has He done?
He bore our grief, carried our sorrows, was pierced for our transgressions and crushed for our iniquities. (Isaiah 53:4–5) He paid for our sin before we asked him to. He took our place and gave us a place in Eternity with Him.
What is He doing?
He is interceding for us (Hebrews 7:25) He hears our prayers (1 John 5:14) He is working out His perfect plan for our lives (Jeremiah 29:11)
What will He do?
He will come again (John 14:3) He will answer your every prayer (Jeremiah 33:3) He will, once and for all, destroy the works of Satan ( 1John3:8)
What more could we want? What more could we ask?
Jesus keeps His promises. All of them.
