Saved by grace and faith alone?

I, Fritjof Persson, invite to a respectful dialogue regarding below summary 'The Doctrine of Christ'. If below is wrong, please show me it from the bible.

How to enter into The Kingdom of God
John3:5=Titus3:3-7=Acts2:38=Heb6:1-2
Substeps How to enter into The Kingdom of God
1) Repent (Luke 13:3).
2) Believe the gospel and that Jesus can save (1Cor15:1-4).
3) Water baptism to wash off the sin by dying and resurrecting with Christ (Rom6, Acts22:16, Col2:11-14,1Peter3:20-21).
4) Holy Ghost baptism evidenced by third party and individual disciple (Mark16:17, John14:23-24, Acts 8:18, 10:46, 11:15-18, 19:6)
5) Hence, the entry into The Kingdom of God is by individual covenant with Jesus. The sinner perform 1-3 and Jesus Christ who is the Quality Inspector of The Repentance confirm by 4.
1John5:8 "The Spirit, and the water, and the blood: and these three agree in one." Hence, blood washed first after water baptism and Holy Ghost baptism.
6) The individual and saving covenant with Jesus Christ which constitutes steps 1-5 (Matt26:26-28, 1Cor11:23-25, John6:53-56, Heb9:14-15, 10:16)
7) Practical entry into The Kingdom of God
Acts8:12-17, 10:44-48, 19:1-6
8) Defence of Salvation:
Rom10:9-10=1John4:15=Rev12:11
Be led by The Holy Ghost, be salty, do not look back, yield fruit, etc
