There can only be one second coming in a persons life.
According to the bible, that is illustrated for us in Acts 3:19-20 where Jesus comes into an individuals life through the Holy Spirit .
This is when an individual repents of unbelief for the first time at their conversion.
There are however other manifestations/visitations of Christ in the New Testament.
Until studied it can seem as though there are many “comings” of Christ.
With study the instances of Jesus coming after conversion can be seen to be different from the Second Coming.
The additional instances are referred to as the Days of the Lord and are times of judgment generally meant for correction, 1 Cor 11:32.
1Co 11:32 But when we are judged, we are chastened of the Lord, that we may not be condemned with the world.
