From these verses of Scripture I see two things: Christians are to preach the gospel and we are to baptize those who are made disciples in the name of the Father, Son and Holy Spirit. But we cannot convert them. This inward experience is the work of the Holy Spirit. We can publicly baptize which is an OUTWARD experience of the INWARD work of God.
1Corinthians 12:13 and Acts 2:38 describe the inward experience of baptism by the Holy Spirit. This is often referred to as being "born again" by the entrance of the Holy Spirit into the heart of a new believer. This is how the believer is "sealed" forever with God's own name as Paul explains in Ephesians 1:13.

Live the gospel. Be obedient to it. Teach it and preach it when I can. Trust that He will strengthen me to do the work He has given me to do. And pray.
