God gives every man every opportunity to know Him, and God always does what is best. Second, God alone knows anyones final relationship to Him. Some cannot accept this. Paul wrote to correct the error of those who on one hand denied that Jesus rose from the dead, and on the other hand baptized the dead. 10 Good deeds are the evidence of a living faith in Jesus.
Faith is passive and active.
The passive side of faith is trusting God to do what we cannot do ourselves, and trusting in God's love and wisdom even when we cannot understand His ways. The active side of faith is obeying God and living by His word and Spirit.
