Can We Enter Heaven Just By Believing in Jesus? Nop! Let us just listen to what Jesus said, “What good is it, my brothers, if a man claims to have faith but has no deeds? Can such faith save him? .... faith by itself, if it is not accompanied by action, is dead.”- James 2:14-17- Then , what should we do in order to enter Heaven as what Jesus said? That's the feasts of New Covenant set by Jesus.
